It starts in late 2016. Havana, Cuba. A piercing
tone, pressure behind the eyes, vertigo, nausea.
For some, the symptoms fade. For others, they
calcify into daily life. Headaches, brain fog,
balance problems that make a staircase feel like
a rolling deck. The reports don't stay in Havana.
They appear in China, Europe, even here in the
United States. Washington gives it a sterile
label. Anonymous health incidents. But a clean
name. doesn't dull the edges. Tonight we let
the record speak. Congress on the stakes. The
Havana sound that launched the controversy. And
sworn testimony on how a directed exposure might
affect the human brain. Plus the on -record claim
that cases happened inside the U .S. Then we
separate the signal from the noise and ask for
the only thing that ends controversy. Data. I'm

Good afternoon and welcome to the Subcommittee
on Counterterrorism, Law Enforcement, and Intelligence.
We're holding this important hearing to examine
anomalous health incidents, otherwise known as
AHIs or Havana syndrome, and discuss the potential
targeting of U .S. government officials and their
families in the homeland and elsewhere. Although
this issue has recently gained significant media
attention, the issues surrounding anomalous health
incidents or Havana syndrome are not new. Dating
back to 2014, a number of U .S. diplomatic, military,
and intelligence officials and their families
have reported major medical symptoms that have
affected their auditory and sensory motor skills.
Two of the U .S. Embassy in Havana, Cuba begin
experiencing similar symptoms. After the reported
incidents in Havana, government officials and
their families began reporting similar symptoms
in the People's Republic of China, Vietnam, Germany,
Austria, Serbia, Australia, Taiwan, Colombia,
as well as here in the United States. Multiple
agencies within the intelligence community have
conducted assessments in an attempt to identify
the factors that cause AHIs or who, if anyone,
is responsible for these incidents. Unfortunately,
none of these studies could conclusively identify
the causes of these incidents. However, the State
Department commissioned a study through the National
Academies of Science, Engineering, and Medicine
that found that, I quote, Unusual presentation
of acute directional or location specific early
phase signs, symptoms and observations reported
by Department of State employees to be consistent
with the effects of directed pulsed radio frequency
energy. Many of the chronic non specific symptoms
are also consistent with known radio frequency
effects such as dizziness, headache, fatigue,
nausea, anxiety, cognitive deficits and memory
loss. Since the National Academy's findings,
Generally, the I see the intelligence community
has stood by their initial findings and maintains
that the origins of these symptoms are still
unknown and not likely to be derived from the
actions of a foreign adversary. Today, we hope
to gain a better understanding of anonymous anomalous
health incidents to address this pressing issue.
It's paramount that we acknowledge the gravity.
of this situation. What you just heard there
is the government putting the stakes on the record,
not a panel show, not a rumor. The chairs lays
out a pattern reaching back to 2014, breaking
into public view in 2016 at the U .S. Embassy
in Havana, spreading across China, Vietnam, Germany,
Austria, Serbia, Australia, Taiwan, Colombia,
and even here in the United States. The symptom
profile repeats sudden directional auditory pressure
events, dizziness, nausea, then lingering cognitive
and vestibule fallout. Crucially, he cites the
National Academic Review Commission by state
early phase location specific symptoms, ultimately
consistent with the effects of directed pulse
radio frequency energy. That's not a verdict.
It's a mechanism flagged as plausible for some
cases. Science speak plausible means worth real
investigation. In the same breath, you heard
the intelligence community's position across
the broad pattern. A coordinated behavior campaign
is unlikely. Those two ideals cannot coexist.
One ask how a subset might happen. The other
ask who did it at scale, different questions,
and ultimately different answers. So we anchor
to what's solid, clusters among trained people,
an international footprint centered on diplomatic
and security hubs, and a deep tradition of classifying
anything that touches sensors or sources. Now
let's move from the abstract to the visceral,
what people said they actually heard. The next
clip is sharp. Pulse is the sound that turned
a weird embassy story into an international debate.
For many, it matched what they heard seconds
before symptoms hit. But discipline matters.
Audio alone is not proof of a weapon. In at least
one widely shared recording, the spectrum and
pulse matched a local cricket. That doesn't erase
injuries. It warns us not to treat consumer audio
as a smoking gun. So we separate experience from
mechanism. The experience is clear. Directional
sensation, pressure tone, or both. Followed by
this vestibule chaos and cognitive fog. Mechanibs
on the table. Audible sonic weapon. A poor candidate.
Airborne sound in the audible range. Dispubates
fast. Reflects unpredictably and isn't easy to
instrument. Next is ultrasound. Possibly a short
range. It doesn't travel through walls cleanly
and it creates hotspots that they survey can
usually map out. Next is directed pulse RF. Uncomfortable.
but plausible for a subset. At certain pulse
characteristics, RF can trigger the fray effect,
perceive clicks and tones inside the head, disturb
vestibule function, and produce concussion -like
symptoms without shrapnel or scorch marks. Skeptics
counter with misattribution under stress, unfamiliar
acoustics, anxiety, messy workups, clusters without
a hidden emitter. Fair, but the Cold War Moscow
signal, low -level microwaves aimed at the U
.S. Embassy for years, keeps the RF door open
conceptually, even if motives there remain debated.
Rather than argued abstractions, your next clip
goes straight to the how and then lands the claim
that cases incurred inside the United States,
clustered around our most sensitive communities.
Mr. Groza, maybe give us an idea of how this
could happen in the United States. Talk us through
a scenario that you've investigated that technology
and location, things that we can put it into
context and understand in layman's terms. In
terms of technology, I'm not an expert in the
technology behind this, but I've read enough
and I'm sufficiently technically minded to understand
that there's more than one way to achieve this
same effect on the human brain. And one of the
most disturbing denials that I've seen in some
of the publications leading up to our findings
being published was an attempt to create the
impression that no technology would allow this
impact on the human brain. That is provably untrue.
experiments that prove that both acoustic in
waves directed waves in the ultrasound primarily
the ultrasound band but also electromagnetic
directed energy especially post nanosecond energy
beams in the millimeter band through something
called the fray effect which converts electromagnetic
energy into an acoustic band wave that can be
within or without or outside of the audible band
can have the same effect on the human brain which
can have long -term concussion -like symptoms
but in really traumatic degree of concussion.
So that is a given and I don't think today we
have the expertise to talk about that but there's
sufficient evidence that is possible. We also
know that the Russian intelligence apparatus
has worked on that and something I would like
to mention as well is that after our publication
a former member of Russia's intelligence community
reached out to me and said this is what we've
been working on since the 80s because we thought
that the Americans were doing that to us. And
we wanted to develop a counter technology for
the same thing. Of course, we're doing that,
which is interesting because Russian intelligence
officers believe they're doing this and American
intelligence officers saying they're not doing
this. Did this individual, this Russian agent
remain anonymous? Unfortunately, for their own
safety, I'll have to leave them anonymous. But
it's a person with in my view, sufficient knowledge
of exactly the the intents, the red lines that
this entity would be exposed to. We know that
members of this unit have engaged with scientists
who have worked on a project called reversal
of epilepsy symptoms through radio waves, which
for anybody known how Russia intelligence formulates
their findings for the public facing domain,
should read them as the exact opposite, creating,
reversing Reversing, essentially, the polarity
might leave you the exact opposite effect, creating
epilepsy symptoms, and so on and so forth. This
interest is long -running for the GRU, for Russia's
military intelligence. One last thing I will
mention is that we found that the only other
place other than among the cohort of American
and Canadian intelligence and the law enforcement
officers who have been affected by this, that
we've seen very similar symptoms, was in a Russian
school in 2017. And we found the evidence to
this similarity in a hacked email box of a military
researcher from the St. Petersburg Institute
for Experimental Medicine working for the GRU.
This institute showed uncanny interest in exactly
what happened in that school where 26 children
complained of exactly the symptoms that we've
received in this investigation from American.
Mr. Syed, is it your belief that these attacks
have happened inside the United States, and if
so, can you? Give us some of the locations and
details that you can share with us. Yes, without
a doubt, they have happened here in the United
States. As I mentioned in my opening testimony,
we know of quite a number, and I would say perhaps
the majority of them were in the Washington,
D .C., Northern Virginia area. There are also
a number, particularly of FBI personnel down
in Florida. But there is no doubt there have
been quite a number of cases here, particularly
relating to the CIA. CIA and FBI most predominantly,
also State Department. You just heard two halves
of the same uncomfortable picture. First, mechanism.
More than one way to achieve similar human effects,
ultrasound, and especially electromagnetic exposures
with pulsed nanosecond scale energy in millimeter
bands. The fray effect explains how EM energy
can be perceived as sound inside the head, even
outside the audible band, and how such an exposure
might produce a concussion -like syndrome with
no blunt trauma. That doesn't prove it happened.
It proves it could. Second, attribution -flavored
leads. A source from the Russian intelligence,
alleging work on this since the 1980s. Initially
as the counter to what they feared the U .S.
was doing. And in 2017, school events where 26
children reportedly showed Havana -style symptoms
at the St. Petersburg Institute, showing unusual
interest. Details that allegedly surfaced in
a hacked research inbox. These are specific leads,
not verdicts. The right posture is curiosity
plus documentation. Finally, the part that brings
all this home. Domestic cases cluster around
Washington, D .C., Northern Virginia, and Florida,
with many among CIA and FBI personnel and family
members. If accurate, this isn't just a foreign
post mystery. It's a Homeland Security problem.
Now let's synthesize this like adults. Capability
is plausible. The physics in public, the Cold
War president exists, and the national academies
flagged directed pulsed RF as the most plausible
mechanism for some early cases. Next attribution
suggested not proven. A prime suspect is in a
conclusion. Diagnostics. Major NIH effort reported
no consistent MRI detect detectable brain injury,
or single biomarker separating patients from
controls, even while many report debilitating
symptoms. If an exposure occurred, the footprint
may be functional or transient, not a neat, lasting
lesion. Now, here's what settles it. Declassified,
sanitized case files, release timestamp sensor
data in any work publication, publish negative
results, and fund controlled ethical research
that can confirm or kill the RF pathway with
modern tools. Right now, the public's stuck and
contradiction. It's serious, but we can't show
you why. It's not a foreign campaign, but we
can't show you how we know that. That's not sustainable.
If this is not a weapon story, prove it with
data. Either way, show your work. Ultimately,
Havana syndrome sets with real -world suffering
meets ambiguous evidence. The recordings that
made it famous may be a cricket. Policy trail,
hearings, compensation, major studies says it's
nothing at all, at least nothing to worry about.
Maybe some subset were targeted by technology
designed to leave no scars. Maybe many warn...
The honest answer is uncomfortable. We don't
fully know yet. The remedy is simple. Declassify,
publish, replicate, and treat the people affected
with dignity of real care while you figure it
out. If you ask me my thoughts on this, I think
we are fighting wars in shadows. Some may love
it, others despise it, regardless of what circumstances
are playing out in the Ukrainian battlefield.
But we as America have been at war with Russia
in a cold sense for a very long time. It's not
outside the realm of possibility that they are
targeting people with weapons. More importantly,
to stop the bridge building that we were in just
a few years ago between the United States and
Cuba. The obviously one is out there. That's
where they put the missiles when we were going
through the Cold War. So for me... I think this
is a cold war symptom. Russia is trying to influence
our policy and we are allowing it to happen.
However, that's all I have for today. Maybe we'll
take another deep dive in the future where I'll
discuss this with my brother Jay on our long
form content. Until then, this is Zero Signal,
