On Tuesday, the House Oversight Committee heard from two experts who have investigated the actions of the secretive government program known as MKUltra that was exposed to the American public in the 1970s.

MKUltra was led by chemist and spymaster Sidney Gottlieb and allegedly included 149 projects from the 1950s to the 1970s.

The program drugged Americans without their knowledge in an effort to develop procedures and chemicals that could be used during interrogations during the Cold War, weakening individuals and forcing confessions through brainwashing and torture.

Stephen Kinzer, a senior fellow in International and Public Affairs at Brown University, and investigative journalist Tom O'Neill warned House members that the sinister CIA experiments could still be happening in secret decades later.

Kinzer said: 'There have been enormous advances in cyber technology, neuroscience, and artificial intelligence. Covert agencies may have access to tools for mind control that Sidney Gottlieb could not have imagined.'

O'Neill added: 'Is it happening today? Did it continue? I don't know. I can't imagine that it didn't, though, because the technology they worked to establish over 20-25 years and spent more money than any operation the CIA ever conducted was successful. I imagine it's being used; I have no evidence it's being used.'

During the hearing, members of the House Oversight Committee openly questioned whether alleged MKUltra mind control experiments to turn ordinary citizens into assassins had been secretly continued and used to target political figures such as President Trump.

Gottlieb believed that to implant a new mind into someone, researchers first had to destroy the one that already existed.

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

According to congressional testimony, MKUltra consisted of at least 149 subprojects, operated across more than 80 institutions and involved 185 non-government researchers.

The CIA secretly funded hospitals and research facilities so unwitting patients could be used as experimental subjects.

'The American people deserve the complete record,' Kinzer told lawmakers.

'The victims and their families deserve acknowledgment, accountability, and justice.'
