Collins said such a conversation was "clearly wrong on the president's part", stopping short of calling it obstruction of justice, a step few Republicans or Democrats in Congress were willing to make on the Sunday-morning political shows following Comey's testimony.
"Well, I'll tell you about that maybe sometime in the very near future", Mr Trump said.
There's a split in the Trump camp over how to approach Comey's testimony, with some supporting Trump's assertion that the conversation never happened, while others say he was too incompetent to be responsible for what he said.
What Comey said about his private February meeting with Trump, and Trump's firing of him on May 9, "gives good reason for the special prosecutor to be pretty aggressive".
Trump Jr.'s statement is a little hard to interpret, but he seems to be indicating that his father did in fact say to Comey that he hoped the FBI could ease up on the Flynn investigation, which was looking into his payments from the Russian and Turkish governments, and that statement should be interpreted a certain way. Comey also said that he considered the comment to be a directive. "So, I don't think a subpoena should be necessary, and I don't understand why the president just doesn't clear this matter up once and for all".
A member of Trump's legal team, Jay Sekulow said "the president said he is going to address the issue of the tapes, whether the tapes exist or not, next week". "Something about the way I was conducting it, the president felt, created pressure on him that he wanted to relieve". Comey shared his memo after he was already fired, he said, adding that he hoped the leak "might prompt the appointment of a special counsel" into the investigation of Russian interference into the 2016 presidential campaign.
That could come from any of several corners. The Washington Post reports that Donald Trump Jr. seemed to tell Pirro that Trump said everything Comey alleged, and that's how you know he wasn't serious.
With a single tweet, Trump also castigated Comey as "a leaker" for giving an account of his conversation with the president to a law professor who shared it with a news outlet. You and I are friends.
The tweet was the second social media lash out from Trump towards his fired Federal Bureau of Investigation director following Comey's dramatic testimony before the Senate Intelligence Committee on Thursday.
Rep. Collins says he feels the conversation was in no way an obstruction of justice. "No more game playing".
