It made sense that Trump and his lawyer would dispute aspects of Comey's testimony that raised questions about whether the president's actions amounted to obstruction of justice.
While White House officials have said the firing was due to concerns about Comey's actions at the Federal Bureau of Investigation, Trump told an interviewer the Russian Federation investigation was one of his concerns in taking the action.
Comey testified June 8 before the Senate Intelligence Committee that Trump had pressured him to drop the FBI's investigation into former National Security Advisor Michael Flynn and demanded his loyalty. But you'll have to determine for yourself whether or not his story changed.
As of two weeks ago, the president's argument was that Comey lied under oath, effectively committing perjury by repeating falsehoods about the scandal. He told Fox News on Friday (US time) his plan to keep Mr Comey in line "wasn't very stupid".
Some of Trump's allies have suggested that Mueller be removed from the probe or step aside, and former House Speaker Newt Gingrich called the former Federal Bureau of Investigation director the "tip of a deep state spear aimed at" the president.
In his interview with Earhardt, Trump reiterated his allegations about the Obama administration's "unmasking and surveillance," though it is unclear that he was trying to imply.
It's important to recognize that Trump is actually regressing.
Mr Trump also said that the people who were hired by the special counsel's office were "all Hillary supporters".
On Thursday, Trump tweeted, "I did not make, and do not have, any such recordings".
Asked whether Mr Mueller should recuse himself from the inquiry because of his friendship with Mr Comey, Mr Trump said: "Well he's very, very good friends with Comey which is very bothersome". But I didn't tape, and I don't have any tape, and I didn't tape.
Republican Representative Mike Conaway, who is leading the House Intelligence Committee's investigation, told reporters Friday morning that Mr Trump's tweet was not a sufficient response.
"I hope she doesn't step down", he said. So whose word is Robert Mueller more likely to believe?
