Rep. Mark Meadows said on Tuesday he is most interested in investigating the eight-day period that led to the appointment of Robert Mueller as special counsel to investigate Russian interference in the 2016 presidential race.

The North Carolina Republican and House Freedom Caucus chairman said key to the effort will be looking at official's "motivations" in the days after President Trump fired James Comey as his FBI director in May 2017.

"From the time of the firing of James Comey to the selection of Bob Mueller as the special prosecutor," Meadows said at a Washington Post Live event. "Those nine days or so in there. There were a number of things going on within the DOJ and FBI, some of which has been reported on, some of which have not."

Meadows, a member of the House Oversight Committee, has been a leading investigator of alleged anti-Trump bias in the upper echelons of the DOJ and FBI.

Of greatest interest to Meadows are Deputy Attorney General Rod Rosenstein and reports that said he discussed using the 25th Amendment against Trump to remove him from office and wearing a wire to secretly record the president.

Meadows said those are not "normal suggestions that would come from the deputy attorney general."

Rosenstein and the Justice Department have disputed that these were ever a serious consideration, but some top officials, including former top FBI lawyer James Baker took it as being a legitimate discussion.

The Justice Department announced on Monday that Rosenstein submitted his resignation letter to Trump, effective May 11, weeks after Mueller wrapped up his investigation into Russian interference in the 2016 election.
