CIA Director John Brennan may have set up a perjury trap for himself, Fox News judicial analyst Andrew Napolitano said on Monday.

Last week, Fox News reported on the existence of a late 2016 email chain in which former FBI Director James Comey told his staff that Brennan insisted that British ex-spy Christopher Steele's unverified research on President Trump's ties to Russia — calling it the "crown material" — be included in the intelligence community assessment on Russian interference in the 2016 election.

Napolitano said if this is true, it would contradict what Brennan told lawmakers under oath.

“I haven't seen the email obviously, but if the email is correct, it directly contradicts what Brennan said under oath, which is another thing for the folks in Connecticut to examine, whether or not the former director of the CIA perjured himself in order to make himself look good,” he said on Fox Business.

Napolitano was referencing U.S. Attorney John Durham, who has been tasked by Attorney General William Barr to review the origins of the counterintelligence investigation into President Trump's campaign.

Brennan, who has accused Trump of committing treason, told the House Intelligence Committee in 2017 that the CIA did not use the dossier and had "no awareness" of any court filing by the FBI.

The dossier by Steele was submitted to the Foreign Intelligence Surveillance Court as part of applications to obtain to authority to wiretap onetime Trump campaign adviser Carter Page.
