A congressional hearing to examine the CIA's secretive mind-control program has been set for this month.

Florida Rep Anna Paulina Luna announced on Wednesday that the Task Force on the Declassification of Federal Secrets will hold a hearing on the Cold War-era MKUltra program on May 13.

The CIA's MKUltra program, conducted from 1953 to 1964, aimed to develop procedures and drugs for interrogations, weakening individuals and forcing confessions through brainwashing and psychological torture.

Luna had pushed to restart congressional hearings on the matter in February, citing a Daily Mail article that reported a newly surfaced document on mind-control experiments had been placed in the CIA’s reading room the year before.

The renewed focus has placed the CIA’s MKUltra program back under the microscope, particularly its use of drugs, hypnosis and psychological testing on human subjects, as well as the death of one of its scientists. 

Dr Frank Olson, a biological warfare scientist, was covertly dosed with LSD at a meeting and died nine days later after falling out of his hotel room in New York City, which was declared a suicide - although some people, including family members, believe he was murdered.

A total of 144 projects were carried out under MKUltra during that period, highlighting the vast scale of the CIA's secret experimentation program.

One such document from 1956 detailed how the CIA considered testing the substances on foreign nationals, but ultimately concluded that 'unwitting testing on American citizens must be continued.' 

A CIA spokesperson previously told DailyMail.com: 'The MKULTRA program ran from 1953 until the lack of productive results and ethical concerns about unwitting testing led to its cessation in 1963.

'CIA is committed to transparency regarding this chapter of its history, including by declassifying information on the programs and making it publicly available on CIA.gov.' The Daily Mail has contacted the CIA for comment regarding the hearing announcement.

MKUltra has become a renewed focus on Capitol Hill, with lawmakers raising concerns about the program's controversial past.

Tennessee Congressman Tim Burchett raised the experiments with the Daily Mail this week, comparing them to what he believes is unfolding within the US scientific community as the White House investigates cases of missing and dead scientists.

'I just go back to the whole concept of MKUltra. They kidnapped people and loaded them up with acid or other mind-altering drugs. They tried to erase their memories,' he said.

'They were sued in court. Then they claimed it didn't exist. In 1975, they ordered records destroyed, and later admitted it had existed but no longer did. Which lies are we supposed to believe?'

Olson was one of at least eight men given LSD on November 19, 1953, as part of an MKUltra experiment, Paul Vidich, Olson's nephew, previously told the Daily Mail.

In statements made during a 1977 hearing about the activities of the CIA, according to Gottlieb, a 'very small dose' of LSD was added to the bottle of Cointreau, which was served after dinner. 

In the days that followed, Olson became paranoid, barely ate and even threw away his wallet, identification badge and money after believing his boss, Vincent Ruwet, had instructed him to do so.

Olson was scheduled to travel to a mental health facility on November 27. At approximately 2.45am on November 28, 1953, Ruwet received a call from Dr Sidney Gottlieb reporting that Olson had died.

Olson's body was later found outside the Statler Hotel, where he had been staying on the 13th floor.

Vidich said his uncle had 'moral qualms about the nature of the work he was doing' and was eventually seen as a security risk.

'Getting thrown out the window was a very convenient way of disposing of a national security risk,' he added. 'To summarize my view, he was murdered.'

His family was not allowed to see his body and was told he had suffered severe facial injuries in the fall and had taken his own life.

Later reports confirmed that Olson had LSD in his system at the time of his death.

The National Security Archive published more than 1,200 pages of MKUltra documents in 2025, detailing the scope of the experiments.

Subjects included criminals, mental patients, drug addicts, Army soldiers and ordinary citizens who were given drugs without their knowledge.

Gangster James 'Whitey' Bulger was among those used as a test subject in 1957 while imprisoned at the Atlanta penitentiary.

He later described experiencing paranoia and hallucinations during the experiments.

'Total loss of appetite. Hallucinating. The room would change shape. Hours of paranoia and feeling violent,' Bulger wrote.

The NSA said in a statement: 'The CIA conducted terrifying experiments using drugs, hypnosis, isolation, sensory deprivation and other extreme techniques on human subjects, often US citizens, who frequently had no idea what was being done to them.'

While most documents were destroyed in 1973, a 1975 investigation led by Senator Frank Church exposed the existence of the MKUltra program.

That investigation sparked widespread public outrage and criticism of the CIA's practices.

It also led to the creation of permanent congressional oversight committees for intelligence agencies.
