The FBI confirmed Saturday it carried out search warrants at a home in Mamaroneck and a Midtown Manhattan apartment, both belonging to the founder of conservative nonprofit Project Veritas.

This confirmation comes a day after a Westchester home with alleged ties to conservative group Project Veritas was searched by agents after the group received a diary that a tipster says belonged to President Joe Biden's youngest daughter, Ashley Biden.

The FBI investigation is now investigating how they were able to get the diary. 

While Project Veritas did not publish it directly, dozens of handwritten pages were posted on the website just before the 2020 election.

Project Veritas says it got the diary ethically from a tipster. 

"The tipsters indicated that the diary had been abandoned in a room in which Ms. Biden stayed at the time…The tipsters indicated that the diary included explosive allegations against then-candidate, Joe Biden," said O'Keefe.

In a video statement, he insisted Project Veritas acted with journalist integrity.

"We attempted to return the diary to an attorney representing Ms. Biden, but that attorney refused to authenticate it. Project Veritas gave the diary to law enforcement to ensure it could be returned to its rightful owner. We never published it," said O'Keefe.

In a video posted on YouTube, James O'Keefe said his organization had received a grand jury subpoena and said current and former Project Veritas employees had their homes searched by federal agents, including his own.

The conservative group is known for using hidden cameras and hiding identities to ensnare journalists in uncomfortable conversations and reveal supposed liberal bias.
