Former Trump campaign figure Carter Page has sued the Justice Department, FBI, and a slew of bureau officials for $75 million, saying he was unlawfully surveilled in the Russian-collusion investigation.

The 59-page lawsuit also named former FBI Director James Comey, former Assistant Director Andrew McCabe, ex-bureau lawyer Kevin Clinesmith, and anti-Trump lovebirds Peter Strzok and Lisa Page as defendants.

Former FBI Deputy Director Andrew McCabe told a Senate committee on Tuesday that he would not have signed an application for a warrant to surveil a former Trump campaign aide had he known it contained inaccurate information.

“If you knew then what you know now, would you have signed the warrant application in June 2017 against Carter Page?” Senate Judiciary Committee Chairman Lindsey Graham asked McCabe.

“No, sir,” McCabe said.

Not until lurid headlines damned Carter Page as a traitor to his country in September 2016, six weeks before the presidential election, did he realize someone was using him to play a dirty political trick.

Reporters had been hounding the energy investor with strangely detailed questions about his ties to Russia. Page told each of them that he was a former US Navy lieutenant, a graduate of Annapolis, an Eagle Scout — hardly a likely protagonist in some cloak-and-dagger drama.

Carter Page, the former Trump campaign aide who was surveilled by the FBI, slapped the Democratic National Committee with a lawsuit, and said that he was just beginning.

Page filed the lawsuit on Thursday at the U.S. District Court in the Northern District of Illinois' Eastern Division.

Surveillance of Page under a FISA warrant has been at the center of the accusations by President Donald Trump and his allies that former officials of the Obama administration abused the power of the government out of political motivations.

A former Justice Department official picked Friday to oversee the FBI’s reforms of its surveillance procedures in the wake of a damning inspector general’s report was one of the many pundits during the Russia probe to defend the bureau’s surveillance of Trump campaign aide Carter Page.

David S. Kris, a former assistant attorney general for national security, was also an outspoken critic of Rep. Devin Nunes and other congressional Republicans who accused the FBI of misleading the Foreign Intelligence Surveillance Court (FISC) in applications to wiretap Page.

The headline on the front page of the New York Times on Nov. 23 read, “Report Is Said To Clear F.B.I. Of Bias Claims,” by Adam Goldman and Charlie Savage.

In a rare public rebuke, the chief judge of the Foreign Intelligence Surveillance Court slammed the FBI Tuesday for misleading it in applications to wiretap a former Trump campaign aide, giving the bureau until Jan. 10 to come up with solutions.

The order came in the wake of findings from Justice Department Inspector General Michael E. Horowitz, who uncovered multiple instances of abuse in his review of the feds’ use of FISA warrants to surveil Carter Page, a one-time foreign policy adviser to the Trump campaign.

WASHINGTON — When a long-awaited inspector general report about the F.B.I.’s Russia investigation became public this week, partisans across the political spectrum mined it to argue about whether President Trump falsely smeared the F.B.I. or was its victim. But the report was also important for reasons that had nothing to do with Mr. Trump.

At more than 400 pages, the study amounted to the most searching look ever at the government’s secretive system for carrying out national-security surveillance on American soil. And what the report showed was not pretty.

Former FBI Director James Comey admitted on "Fox News Sunday" that the recently released Justice Department Inspector General’s report on the launch of the FBI’s Russia investigation and their use of the surveillance process showed that he was "overconfident" when he defended his former agency's use of the Foreign Intelligence Surveillance Act (FISA).
