This afternoon, shortly after the inauguration of President Trump the White House ordered a freeze of all pending regulations.
He showed side-by-side photos from Trump's inauguration and President Barack Obama's inauguration in 2009 to compare crowd sizes.
His latest skirmish with the press over the size of his inauguration crowd grabbed the most headlines.
Trump and members of his team are often critical of the media, accusing its members of biased and dishonest coverage against him.
"It's really not about crowd size", Priebus replied.
Top White House aide Kellyanne Conway told NBC's "Meet the Press " Sunday that Spicer provided "alternative facts" to reporters during his press briefing on Saturday afternoon".
Host Chuck Todd though fire back, saying alternative facts "are not facts".
Priebus argued that there was a media conspiracy to delegitimize Trump's presidency, claiming that media outlets were incorrect to report on issues including Russia's meddling in the U.S. presidential election.
"We're going to fight back tooth and nail every day and twice on Sunday", Priebus said.
Trump, who lost the popular vote to Democrat Hillary Clinton by almost 3 million votes, made no mention of Russian Federation in his first visit to the Central Intelligence Agency on Saturday.
"If we are going to keep referring to our press secretary in those type of terms, I think we are going to have to rethink our relationship here", she said.
Several of Spicer's statements about Friday's turnout were challenged in photographs and media reports that cited crowd count experts.
He also said it was the "largest audience to ever witness an inauguration - period - both in person and around the globe".
"You talk about honesty, and say that this was about honesty", Wallace said.
His initial tweet said he was "under the impression that we just had an election", asking: "Why didn't these people vote?" "He's president", Senate Democratic leader Chuck Schumer said on ABC's "This Week".
