WASHINGTON — Carter Page, an ex-foreign policy adviser to Donald Trump's campaign whose past contacts with Russia have made him a subject of congressional and federal inquiries, said Wednesday he plans to testify publicly before the House Intelligence Committee in June as part of the panel's investigation of Russian interference in last year's election.

Committee officials said they could not confirm whether Page will appear next month. Page said details of his testimony are "still being worked out" with the committee, which is investigating possible collusion between the Trump campaign and Russian officials.

Page said he would not be asserting a Fifth Amendment privilege against self-incrimination as was invoked earlier this week by former national security adviser Michael Flynn.

“I am an open book,’’ Page told USA TODAY. “Compared to the incomplete lies that defined me in the secret criminal justice system and the rest of the (intelligence community) last year, any actual facts and truths I can illuminate will be a giant leap in the right direction.’’

In April, it was disclosed that the FBI had obtained a federal court order last summer to monitor Page’s communications as part of its investigation into possible collusion between the campaign and Russia.

Page has denounced the surveillance effort, which was first reported by The Washington Post.

Last March, during a meeting with the Post’s editorial board, Trump referred to Page as a member of his national security advisory council.

Page made it clear that one of the reasons he wants to appear before the House Intelligence Committee is to rebut testimony from former CIA director John Brennan, who testified before the panel Tuesday.

"The vast majority of the open session testimony by Mr. Brennan and other Clinton/Obama regime appointees who have recently appeared before your committee loyally presented one biased viewpoint and base of experience," Page wrote Tuesday in a letter to Rep. Michael Conaway, R-Texas, who is leading the panel's Russia probe, and Rep. Adam Schiff of California, the committee's senior Democrat.

"When I have my turn next month, I look forward to adding some accurate insights regarding what has really been happening in Russia over recent years, including 2016," Page wrote.

Brennan testified Tuesday that he doesn't know whether there was collusion between the Trump campaign and Russian officials in the 2016 election, but he left office in January with "unresolved questions" about whether Russia had been successful in getting Trump campaign officials to act on its behalf "either wittingly or unwittingly."

"I encountered and am aware of information and intelligence that revealed contacts and interactions between Russian officials and U.S. persons involved in the Trump campaign that I was concerned about because of known Russian efforts to suborn such individuals," Brennan said. "It raised questions in my mind about whether Russia was able to gain the cooperation of those individuals."

Brennan turned over that intelligence information to the FBI, which used it as the basis for its own investigation. Former FBI director James Comey was leading that probe until President Trump abruptly fired him two weeks ago. Deputy Attorney General Rod Rosenstein last week appointed former FBI director Robert Mueller as special counsel to take over the investigation.

Page's decision to testify before the House Intelligence Committee wasn't the only development that raised eyebrows in Washington. According to CNN, Attorney General Jeff Sessions, who recused himself from overseeing the FBI's probe into Russia's interference with the 2016 election, did not disclose meetings with Russian officials last year when he applied for security clearance.

Sessions, CNN's report adds, failed to disclose the interactions he had with Russian Ambassador Sergey Kislyak on the form. Known as the SF-86, the form requires applicants to list "any contact" with any "foreign government" or its "representatives" over the past seven years, CNN reports, citing officials.

Page, who owns a consulting firm called Global Energy Capital, joined Trump's campaign in March 2016 and then traveled to Moscow a few months later to give a speech at the New Economic School advocating better U.S.-Russia relations.

In April of this year, Page told ABC News anchor George Stephanopoulos that he had "no recollection" of discussing the possible easing of U.S. economic sanctions against Russia but that "something may have come up in a conversation" during his trip to Moscow in July 2016.

“I have no recollection, and there’s nothing specifically that I would have done that would have given people that impression," Page said on Good Morning America.

Page suggested that Flynn’s decision to seek Fifth Amendment protection was likely prompted by an investigation grounded in partisan politics.

“My take is that after his Cleveland (Republican convention) speech, he had a big target on his head,’’ he said, referring to Flynn’s appearance where he led the crowd in chanting: “Lock her (Hillary Clinton) up!”

The House Intelligence Committee is one of four congressional committees that is currently investigating Russia's interference in the U.S. presidential election and possible collusion between the Trump campaign and Russian officials.
