Following former FBI Director James Comey’s testimony before the Senate Intelligence Committee, Charles Krauthammer said it was a "bad day" for both President Donald Trump and Comey.

He explained that Comey stopped short of alleging Trump committed obstruction of justice in the FBI's Russia probe, but he nonetheless accused the Trump administration of defaming him and said comments made about his competency “were lies, plain and simple.”

He added that Trump's personal attorney Marc Kasowitz did not adequately rebut Comey's testimony during a brief statement following the hearing.

"I don't think Comey had a good day for himself, but surely the president had a bad day," Krauthammer said, adding that the hearing damaged Trump's credibility.

As for Comey, Krauthammer said that he came off as "cowardly" for admitting that he caved in to a request from former Attorney General Loretta Lynch to refer to the Hillary Clinton email probe as a "matter," not an investigation.

He added that the central question of the Russia investigation is: If Comey thought Trump committed obstruction of justice in the FBI's probe, then why didn't he take action?

"Why didn't you resign? Why didn't you even bring it up with the president or anybody in [the Department of] Justice?" Krauthammer said.
