The Republican-led House oversight committee said Wednesday it plans to invite fired FBI Director James Comey to a May 24 hearing, amid questions on whether President Trump tried to interfere with the FBI investigation into Russia's meddling in the 2016 race.

Committee Chairman Rep. Jason Chaffetz, R-Utah, tweeted that he's asked Comey to testify at the hearing. He added, "I still need to speak with him," suggesting the hearing is not yet set in stone.

Trump’s firing last week of Comey raised concerns about whether the president was trying to sideline the Russia probe, which is examining Russian ties to his 2016 presidential campaign.

Adding to the furor, The New York Times first reported Tuesday on claims that Trump asked Comey to end a bureau probe into then-National Security Adviser Michael Flynn's Russia contacts.

The White House on Wednesday disputed the account of the Trump-Comey conversation on Flynn, fired by Trump for concealing at least one conversation with the Russian ambassador.

“That was not an accurate representation of that meeting,” White House Press Secretary Sean Spicer said of the report, based on a source who purportedly had Comey’s notes or memo of the exchange.

Fox News also confirmed Wednesday the existence of the Comey memo. Sources close to Comey and who are familiar with the memo said the Times account is accurate.

A former government official also told Fox News that Comey was known to be a prolific memo writer, and it would not be surprising if more Comey memos emerge in the coming days.

Chaffetz has also asked the FBI for all information on Comey's memos.
