Mr Trump has said Mr Comey told him three times he was not a target of the FBI inquiry, fuelling accusations the president was interfering in the investigation. Later, the president and his advisers said Mr Trump had planned to fire Mr Comey since taking office.
Regarding Trump's possibly threatening tweet, Spicer insisted the president had merely stated "facts".
"That includes investigating the nature of any links between individuals associated with the Trump campaign and the Russian government, and whether there was any coordination between the campaign and Russia's efforts", Comey added.
Both he and deputy press secretary Sarah Huckabee Sanders were put in a tough spot by Trump's own evolving story over the last few days, struggling to reconcile what they'd seemingly been told earlier (and Trump's own letter to Comey saying he'd taken the advice of the DOJ to fire him) with Trump's Wednesday comments.
Mr Trump also cited comments from James Clapper, the director of national intelligence, at a Senate hearing earlier this week that he was not aware of any evidence demonstrating collusion between Trump's campaign and Russian Federation. She isn't. And those two differences explain why Republicans, especially those in the White House, were foolish to think that Democrats would not criticise the firing of Federal Bureau of Investigation director James Comey.
Spicer also denied reports that Trump solicited a loyalty pledge from Comey during their dinner earlier this year.
In addition to any possible tapes, the two congressmen request "all documents, memoranda, analyses, emails, and other communications relating to the President's decision to dismiss Director Comey" by May 25.More news: Massive cyberattack hits 99 countries, cripples systems worldwide

Nonetheless, the White House has continued to use Clapper's Meet the Press remark as a talking point even after his clarification.
But he also said, "In fact when I chose to just do it, I said to myself, I said, 'You know, this Russian Federation thing with Trump and Russian Federation is a made-up story, it's an excuse by the Democrats for having lost an election that they should have won'".
Acting FBI Director Andrew McCabe testified in front of the committee on Thursday.
"This is our job", Burr said.
"I don't know if there was collusion or not", Clapper said during an interview Friday with MSNBC. "I will have group conference calls with multiple witnesses", Watts said.
By way of explanation for the conflicting versions given out by the White House on the Comey firing, Trump said, "As a very active President with lots of things happening, it is not possible for my surrogates to stand at podium with ideal accuracy", while once again accusing the "fake media" of projecting the story that there was collusion between the Russians & Trump campaign which was "fabricated by Dems as an excuse for losing the election".
"There are archaic rules, and maybe at some point, we're going to have to take those rules on, because for the good of the nation, things are going to have to be different", Trump told Fox News.
That explains why he then asked the Justice Department to come up with a rationale for sacking him, not caring that his embrace of Comey's questionable handling of the Clinton email probe as the pretext for firing him would be met with instant suspicion.
