Kremlin spokesman Dmitry Peskov said earlier Moscow did not have official contacts with Trump's team during the presidential campaign.
October 28, 2016: Days before the election, Comey informs Congress by letter that he is reopening the investigation into Clinton's email practices based on new evidence, citing the discovery of emails on a laptop used by a top Clinton aide. "I think we had some mixed messages out there that didn't help matters at all".
Jeff Mason, the president of the White House Correspondents' Association, responded to the president's tweets, saying that the White House briefings and press conferences "conducted in full view of our republic's citizens, is clearly in line with the spirit of the First Amendment".
May 12, 2017: Trump tweets that Comey "better hope that there are no "tapes" of our conversations before he starts leaking to the press!"
"Well, the difficulty, and I look at this as former prosecutor, can you prove obstruction based on the president's own words when we don't know whether we can believe this president?"
The White House also changed its narrative about whether the president had made a decision to fire Comey based on the recommendations by Rosenstein and Attorney General Jeff Sessions.
Former acting Attorney General Sally Yates - who was sacked by Trump after she refused to defend his travel ban - and former Director of National Intelligence James Clapper also testified in front of a Senate subcommittee on crime and terrorism on Monday.

As Mr Trump works to fast-track Mr Comey's successor, lawmakers from both parties urged him to steer clear of any politicians for the job and say he must "clean up the mess that he mostly created".
Garland was President Barack Obama's pick to replace Supreme Court Justice Antonin Scalia after Scalia's death past year.
Trump is using his platform to attempt to intimidate and silence those who refuse to pledge loyalty to him. While Comey turned down a request to testify this coming Tuesday, a "close associate" of Comey's did tell The New York Times he is willing to go before the Intelligence Committee, he just wants the testimony to be public.
At a closed-door meeting Thursday with the two leaders of the Senate intelligence committee, Rosenstein and Boente laid out how the FBI plans to work with the panel, trying to ensure its investigation doesn't conflict with that of the committee as administration officials and lawmakers interview witnesses and obtain documents on their parallel investigations.
Graham also said he would consider a special prosecutor if Comey's recounting of the meeting was accurate. He simply stated a fact.
Later, the president and his advisers said Trump had planned to fire Comey since taking office. "The exchange that took place with Comey, whichever version you believe, raises very, very serious questions about attempts to pressure an FBI director investigating wrongdoing potentially implicating the president". "I have my subpoena pen ready", Chaffetz tweeted. Declining comment on a Garland nomination, Schumer left open the possibility that Democrats might withdraw support for a new Federal Bureau of Investigation director unless the Justice Department names a special prosecutor. His broad mandate could well include Trump's firing of Comey. If they exist, Congress needs to get them.
