Washington (CNN) The Trump administration is refusing to explain how it has managed to bury its Russia investigation, as a key Republican member of Congress called for a congressional investigation.

“This is a disgrace,” Rep. Mark Meadows, R-North Carolina, said Wednesday on CNN.

“The president needs to explain why he is still trying to hide this from Congress.”

“This has gone on for so long that it’s time to end it,” Meadows said.

The House Oversight Committee has scheduled a hearing for Friday to look into the White’s response to the investigation.

The White House did not respond to CNN’s request for comment on Wednesday.

In late June, Trump fired FBI Director James Comey, saying he was taking action on the investigation into whether his former national security adviser Michael Flynn had improperly disclosed classified information.

Trump has repeatedly denied that he discussed Flynn’s potential ties to Russia.

“I fired Comey for the same reason he was fired,” Trump said at a press conference in the Rose Garden on July 5.

“I think it was totally a mistake, and he was doing a great job.”

“The president of the United States has never, in my opinion, made a mistake in his entire life,” he added.

“He’s a very good man, he’s a great man.

Earlier this month, the Senate Intelligence Committee released a letter that showed the FBI had not interviewed Flynn for nearly a year and had only interviewed him about three times. “

So, I don’t think there’s any reason for the president to try and cover it up.”

Earlier this month, the Senate Intelligence Committee released a letter that showed the FBI had not interviewed Flynn for nearly a year and had only interviewed him about three times.

That letter said that in a June 2017 interview, Flynn said he “wanted to talk to you about his discussions with the Russian ambassador about U.S. sanctions on Russia.”

But the White and the FBI did not provide documents to the committee that corroborated Flynn’s statement.

In the letter, the FBI director said that Flynn did not recall giving a specific conversation or setting of the meeting but that he believed it was related to sanctions and that “the topics discussed were generally related to the sanctions.”

The committee also found that the FBI conducted an investigation into Flynn’s business dealings after Trump fired him, but that no evidence of wrongdoing was uncovered.
