The US president said he would go under oath to give his version of what happened between him and the FBI Director he fired.
The reporter then continued: "So he [Comey] lied about that?"
Among his disagreements with Comey, Trump said he never asked Comey for an oath of loyalty. The "collusion" reference is apparently to the White House's long-running contention that there is no evidence Trump's campaign colluded with Russian attempts to undermine the election.
If that was an order, rather than a suggestion, Mr Trump may be vulnerable to the charge of obstruction of justice. A president can be charged after leaving office. "When [Trump] tells you to do something, guess what, there's no ambiguity in it", Trump Jr. said in an interview with Fox News" Jeanine Pirro.
LANKFORD: It does, actually, only because it's this president.
CORNISH: And of course then there's the firing itself, with the president telling NBC, you know, I chose to do it.
"No I didn't say that", Trump insisted. You don't see a tie there.

The president was twice questioned on Friday about whether there are tapes of his and Comey's discussions.
Panama severs diplomatic ties with Taiwan, recognises 'only one China'
Panama's termination of bilateral relations with Taiwan means there are only 20 countries that recognise Taiwan. Diplomatic tussles between Taiwan and Beijing eased under the island's previous Beijing-friendly government.
The recordings came for reference at Comey's testimony and his remarks about them, in response to a question, went viral on social media: "Lordy, I hope there are tapes". And my judgment was I needed to get that out into the public square.
"Frankly, James Comey confirmed a lot of what I said".
They also asked McGahn to tell the committee whether the White House has or has ever had recordings of Comey's conversation with Trump - and put a June 23 deadline on the information.
A White House source said: 'At the moment this is a case of "he said, he said".
The Justice Department has denied that a third meeting occurred. Do you agree with this idea and that that's acceptable for a president, especially a president with some experienced staff?
"When it comes from the president, I took it as a direction".
The FBI director is a very different role than a cabinet official. "The president has the authority to tell the director of the FBI to stop an investigation".
Standing with Iohannis, a North Atlantic Treaty Organisation partner, Trump at last confirmed his commitment to the alliance's mutual defence pact, Article 5, uttering words he deliberately did not say when he spoke at NATO's gathering in Belgium last month. "And some of the things he said just weren't true". However, Comey didn't say that the president's words were part of an effort to obstruct his investigation.
So it was clear the investigation did not slow.
Trump Jr. argued Saturday that Comey was being disingenuous in his description of the meeting. So we're trying to interpret the difference between frustration and trying to actually impede the process. Thank you for speaking with us.
