The Washington Post also reported that the former Federal Bureau of Investigation director is looking into whether Trump obstructed justice in his personal conversations with Comey and other key officials.
The tapes saga began in May, just days after Trump fired Comey, who then was leading an investigation into Trump associates' ties to Russian officials.
A special counsel appointed by the Justice Department is now investigating the issue.
The House Intelligence Committee is said to be investigating whether individuals affiliated with President Trump's 2016 campaign received stolen voter data obtained by election hackers during last year's race, according to multiple reports. He also said he hoped that the alleged tapes of his conversations with Trump do exist. There apparently are no tapes that could confirm what exactly happened in those chats.
Tapper opened a monologue on his program, "The Lead", on Thursday recapping the drama around Trump's suggestion that there were "tapes" of his conversations with FBI Director James Comey, who Trump fired on May 9.
The admission threw a new twist into allegations, fed by Mr Comey's own claims, that Mr Trump wanted the Federal Bureau of Investigation to pull back on its probe into the Russian Federation scandal. "Was he trying to intimidate or silence James Comey?".
But the president has steadfastly refused to clarify whether any tapes existed.
"Oh, you're going to be very disappointed when you hear the answer", Trump said.

On June 9, the House Intelligence Committee investigating whether or not there was Russian meddling with the U.S. elections sent a letter to the White House asking whether these tapes exist. He added that health care is "a very complicated situation from the standpoint, you do something that's good for one group but bad for another".
"Also, we need to continue to ask others, since, unfortunately the president has in the past tweeted things that simply did not square with the facts".
Under a post-Watergate law, presidential recordings belong to the people and eventually can be made public.
Three of the lawyers have been identified as donors to Democrats, including Clinton and former President Barack Obama.
Trump's critics immediately seized on his admission on the tapes to raise concerns about his suitability for the Presidency.
"Now it is unclear why the President made that initial tweet. But he seems to have a capacity to outdo himself", Connecticut Democratic Sen.
"To say he has no idea is absolutely preposterous and really an insult to the intelligence of the American people", Blumenthal said. "He was - he did admit that what I said was right".
