Kellyanne Conway sparred with NBC's Chuck Todd on Sunday as she defended White House press secretary Sean Spicer for providing "alternative facts" to the press during a briefing this weekend.

Spicer appeared in the White Hosue briefing room late Saturday evening to slam the media's "shameful" coverage of the crowd size at President Trump's inauguration. Reporters later mocked him for criticizing the press over what they felt was a trivial matter.

"Sean Spicer, our press secretary, gave alternative facts to that," Conway told Todd after he accused Spicer of inflating the inaugural crowd size.

"Look, alternative facts are not facts," Todd said. "They're falsehoods."

Todd later said Spicer's press briefing was a "ridiculous" affair, which Conway did not take kindly to.

"Your job is not to give your opinion, Chuck," Conway fired back. "Your job is not to call things 'ridiculous' that are said by our press secretary and by our president."

She continued, "Think about what you just said to your viewers. That's why we feel compelled to go out and clear the air and put alternative facts out there."
