The report said Comey could testify as early as next week.
The New York Times first reported in February that Comey wrote a memo saying Trump had asked him to shut down the investigation into Flynn, the former national security adviser.
The memo reportedly said that Trump told Comey, “I hope you can let this go.” The President reportedly was referring to Comey’s FBI’s investigation into Flynn.
Flynn was forced to resign February 13, one day before the conversation between Trump and Comey depicted in the memo.
A Comey associate, who wasn’t authorized to discuss details of the testimony, told The Associated Press that Robert Mueller III, who was appointed earlier this month by the Department of Justice to lead the government’s inquiry, is allowing Comey to make certain statements.
A spokesman for Mueller said he did not have any information on Comey’s potential testimony, or whether Mueller has cleared the former FBI director for public testimony.
Congress is currently out of session until next Tuesday. No date for testimony in front of the intelligence committee has been set.
“The committee welcomes the testimony of former Director Comey, but does not have an announcement to make at this time,” a Senate Intelligence Committee spokeswoman said.
The House panel pursuing its own investigation of the Trump campaign and possible ties to Russia also has sought information from Comey, asking the FBI to turn over documents related to his interactions with both the White House and the Justice Department.
Trump has continued to deny allegations that his campaign collaborated with Russia ahead of the Presidential election. Early Wednesday morning, the President tweeted “Witch Hunt!” in reference to testimony by Comey and former CIA Director John Brennan before Congress on the topic.
But later in the day, the White House showed it was beginning to offload the Russia crisis to Trump’s longtime personal attorney, Marc Kasowitz.
During Wednesday’s press briefing, Sean Spicer refused to answer a reporter’s questions about developments in the probe. He said all questions regarding Russia must be directed to Trump’s outside counsel. It marked the first time the White House officially acknowledged that outside counsel had been retained.
