"However, because of the many false statements made by White House officials this week, we are compelled to ask whether any such recordings do in fact exist. If so, we request copies of all recordings in possession of the White House regarding this matter."

The request came hours after Trump suggested on Twitter that there may be tapes of conversations from Comey's visit to the White House in January.

"James Comey better hope that there are no 'tapes' of our conversations before he starts leaking to the press!" Trump wrote.

It's not clear if such recordings actually exist. When White House press secretary Sean Spicer was asked about the tapes at his Friday press briefing, he demurred, saying "the president has nothing further to add on that."

In addition to the recordings, Cummings and Conyers are also requesting from the White House all documents, emails and other communications regarding Trump's decision to fire Comey.

Another Democrat on the House Oversight Committee, Rep. Raja Krishnamoorthi (D-Ill.), sent McGahn a letter of his own on Friday, also requesting that the White House turn over the recordings.

Democrats have amped up pressure on the Trump administration since Comey's ouster on Tuesday. Since then, the White House has released a series of statements attempting to explain the president's decision to oust the FBI head.

Some of those statements, however, have been repeatedly contradicted by competing accounts of the decision, including that of Trump himself.
