Expert witnesses stunned a congressional hearing Tuesday by testifying that Jack Ruby and Charles Manson were “MKUltra assets,” injecting fresh controversy into the decades-old debate over the CIA’s infamous mind-control program.
The explosive claims emerged during a House hearing examining the CIA’s Cold War-era behavioral modification program, which has long been shrouded in secrecy despite decades of declassified records confirming the agency conducted unethical human experimentation involving LSD, hypnosis, and other psychological techniques.
The testimony immediately drew attention from Rep. Anna Paulina Luna (R-Fla.), who announced she would press the CIA to release any remaining MKUltra records.

“According to today’s expert witnesses: JACK RUBY AND CHARLES MANSON WERE MKULTRA ASSETS,” Luna wrote on X. “I am following up directly with the CIA to demand the full release of MKUltra records. The American people deserve and will be delivered the truth.”
The assertions are among the most provocative made during the hearing. While MKUltra itself is an established historical program, no publicly released CIA documents have conclusively demonstrated that either Ruby or Manson served as MKUltra assets.

Researchers have debated both figures for decades.
Ruby’s connections, psychological evaluations, and later treatment by psychiatrist Dr. Louis Jolyon West—who had ties to government-funded behavioral research—have fueled speculation among JFK researchers.
Likewise, Manson’s interactions with psychiatrists and the broader counterculture milieu of the late 1960s have led some authors to question whether elements of his story intersected with intelligence-linked research programs.
However, previous official investigations have not concluded that either man was controlled or recruited through MKUltra.
The hearing nevertheless renewed calls for greater transparency surrounding the CIA program, particularly because many MKUltra records were intentionally destroyed in 1973, leaving historians to reconstruct the project from surviving financial documents and scattered files.
Whether additional classified records still exist remains an open question.
For critics of the intelligence community, Tuesday’s testimony underscored the need for further declassification. For skeptics, the hearing highlighted the distinction between provocative witness testimony and historically verified evidence.
If Rep. Luna’s request results in the release of additional MKUltra documents, the debate over one of the CIA’s most infamous programs could enter a new chapter.
