The Republican chairman of the House Oversight and Government Reform Committee has asked the FBI to turn over “all memoranda, notes, summaries, and recordings” that detail communications between the agency’s former director, James Comey, and President Trump.

Rep. Jason Chaffetz (R-Utah) made the request in a Tuesday-night letter to the FBI, giving the agency until May 24 to produce the records. Chaffetz noted on Twitter that he’s prepared to subpoena the records, if necessary.

Asked by The Washington Post’s Carol D. Leonnig what his goal was in requesting the records, Chaffetz said: “Truth. Let’s see how real these memos are. … And see where they take us.”

Chaffetz added that he wasn’t prejudging the case.

“I simply want to see the documentation,” he told The Post. “We will let the evidence take us where it does.”

The request follows news reports that Trump asked the FBI to drop its investigation into former national security adviser Michael Flynn and urged Comey instead to pursue reporters in leak cases.

Chaffetz announced last month that he will not run for reelection in 2018, stirring speculation that he may run for governor in 2020. Last year, the Utah Republican told the Deseret News of Salt Lake City that he would “take a serious, serious look” at a gubernatorial bid in Utah once his term as chairman of the House’s primary investigative committee expired.
