The president said he would be willing to tell that to the newly appointed special counsel in the Russian Federation investigation, Robert Mueller.
Comey testified he had nine one-on-one conversations with Trump - and detailed each in memos just after they met for fear that the president would subsequently lie about their interactions.
Trump was addressing reporters for the first time since Thursday's explosive testimony in which Comey branded the president a liar, and said he was sacked over his handling of the Federal Bureau of Investigation probe into Russian election meddling.
Though Comey noted he had had one classified conversation with Trump, which he called "brief and entirely professional", he did not admit to leaking information about it to the press.

Meanwhile, Democratic lawmakers and other critics say Comey's clams that Trump leaned on him to somehow drop the Russian Federation investigation could amount to an obstruction of justice.
In a Capitol Hill hearing room, the astonishing tableau unfolded of a former FBI director accusing the White House of "lies, plain and simple" and asserting that when the president suggested dropping an investigation into his former national security adviser, "I took it as a direction".

May hopes to make an ally of Macron before the formal opening of Brexit negotiations, which is expected to take place next week. May tried to reassert her shattered authority at the weekend by announcing her new cabinet -with no changes among her top team.
Many Democrats still blame Comey for Clinton's loss, leading Trump to apparently believe they would applaud him for firing Comey.
The House intelligence committee is seeking any tapes of the conversations. "Totally illegal? Very 'cowardly!'" Trump wrote on Twitter.
"He gave his notes to a Columbia law professor because he wasn't man enough to give the notes directly to the media", Lewandowski told NBC's morning show "Today."Though Trump has lambasted Comey as a "leaker", he also claimed "total and complete vindication" following the ex-FBI chief's testimony, focusing on Comey's confirmation that Trump was not personally being probed".
"I would be glad to tell him exactly what I told you", Trump said. "I'm not going to say, "I want you to pledge allegiance".
"Mr. Comey has now admitted that he is one of these leakers", he said. "I am also deeply concerned about the Attorney General's role in firing Director Comey in light of his recusal from the Russian Federation investigation".
Still, the president's lawyer says he'll file a complaint with the justice department, CBS2's Tony Aiello reported. These were the notes he asked a friend to leak to the press.
