Reporter to White House press secretary: Do you promise to 'always tell the truth'?

During the first official White House press briefing of President Donald Trump's administration, a reporter asked White House Press Secretary Sean Spicer promise to "always tell the truth" and "never to knowingly say something that is not factual."

ABC's Jon Karl posed the question after Spicer was criticized over the weekend for making an impromptu statement berating the media for its coverage of the inauguration and then leaving the room without taking questions. But Spicer afforded reporters that opportunity Monday, answering questions from the podium for more than an hour.

While some reporters sought to clarify where administration officials received their information that led them to declare Trump's inauguration had "the largest audience ever to witness an inauguration” in person and around the world, Karl pressed Spicer on a much more serious topic.

"Is it your intention to always tell the truth from that podium and will you pledge never to knowingly say something that is not factual?" Karl asked.

Spicer replied: "It is. It's an honor to do this and yes, I believe we have to be honest with the American people. I think sometimes we can disagree with the facts. There are certain things that we may not fully understand when we come out, but our intention is never to lie to you."

"I'm going to come out here and tell you the facts as I know them, and if we make a mistake I'll do our best to correct it," Spicer added.
