Carter Page, who briefly served as a foreign policy advisor to the Trump campaign, dropped off documents subpoenaed by the House and Senate Intelligence Committees on Thursday.

The Manhattan energy investor and broker told reporters the committees had requested “irrelevant” documents from his business and personal records, according to a report by The Hill.

Page testified to the House Intelligence Committee in the first week of November, and just days later, the committee released the full text of his conversation. In that testimony, he denied any wrongdoing in his contacts with Russia.

Page has also been one of the earliest targets of the ongoing congressional investigations into Russia’s meddling in the 2016 election, in all likelihood because he was mentioned frequently in the “Russian dossier,” which is known to have landed in the hands of congressional and FBI sources in the late summer and early fall of 2016.

Page took a trip to Russia in 2016 that has been of interest to investigators.

He also continues to interact with the committees without an attorney. An earlier report this year said Page had interviewed several times with the FBI in March, and Page said all of those meetings were conducted without an attorney.

"It's more witch-hunt style on this side, whereas they act more professional on the House side," Page said as he was leaving a Senate office building.

Page has been a constant critic of the dossier, which, according to a Washington Post report earlier this year, may have been used as a partial basis for the FBI to obtain a warrant to surveil him sometime in the latter half of 2016.
