Sean Spicer Shares Trump's Reaction to Emmys Cameo and Insists He Never 'Knowingly' Lied

"He was very supportive," Spicer told "Good Morning America" in an interview that aired on Thursday morning. "He thought I did a great job. It was very reassuring."

And maybe not-so-surprising is the president's former White House press secretary stating he never lied to the American people.

"I've not knowingly done anything to [lie], no," Spicer said.

"I've made mistakes. There's no question, I think we all do," he said. "Some of them I've tried to own very publicly and in some cases there were things that I did, until someone brought it up, I said, 'Gosh, I didn't realize that that was a mistake. I'm sorry about that.'"

Spicer shocked the star-studded Emmys audience and viewers tuning in from home Sunday night when he rolled out on his mobile podium after host Stephen Colbert asked if there was anyone in the house who could help him figure out how big the audience watching was. The joke, of course, was mocking Trump's exaggerated claims about the size of his inauguration crowd in Washington, D.C., last January.

"This will be the largest audience to witness an Emmys. Period. Both in person and around the world," Spicer joked Sunday during the bit, which many viewers were not comfortable with.

Looking back at his claims about the size of Trump's inauguration crowd, Spicer said it would have been helpful to have "had more facts at hand" the day of his press conference addressing the president's bold claims.

"I think it might have been better to be a lot more specific with that we were talking about in terms of the universe and not focus so much on photographic evidence," he said.

Although many Americans were vocal in their outrage that Hollywood made a joke out of Spicer's role in lying to the American people during his tenure in the Trump administration, Spicer doesn't seem to mind the backlash.

"I feel very good with my image. I'm very happy with myself," he said. "I am able to go out and explain a lot of things now, but I'm not on a tour. I'm out having some fun."
