Former CIA director John Brennan has admitted the infamous letter signed by 51 former intelligence officials falsely saying Hunter Biden's laptop was Russian disinformation 'was political'.

Brennan, the CIA chief during Obama's administration made the admission during his four-hour testimony to House Judiciary Committee investigators behind closed doors last week', Fox News reports.

Brennan's deposition comes as former Director of National Intelligence James Clapper is expected to give testimony on May 17.

Both Brennan and Clapper signed a letter by 51 former intelligence officials who claimed Hunter's laptop had 'all the classic earmarks of a Russian information operation'.

An email shows Brennan agreeing to have his name added to the letter of signatories by the then acting CIA Director Mike Morell. 

Hunter's laptop included explicit photos of the troubled Hunter Biden naked, with prostitutes, and taking drugs, as well as multiple emails and texts between the 53-year-old and his father. 

It comes as a bombshell Republican report has claimed that the CIA was actively involved in getting the 51 signatures on the letter, which the House Judiciary Committee allege was part of a 'political operation to help elect' Joe Biden in November 2022.

It alleges that a CIA employee 'may have helped in the effort to solicit signatures for the statement' and accuses former Deputy CIA director and Acting CIA Director Mike Morell and the Biden campaign of conspiring to quickly get the letter approved.
