Scaramucci was originally considered for a White House post, but his potential business conflicts held him back.
This news was announced by Anthony Scaramucci at the White House press briefing on Friday, July 21.
"Anthony Scaramucci is somebody who has been an incredible asset to President Trump all during the campaign, the transition and now he's one of the killers on TV", said Counselor to the President Kellyanne Conway while on Fox News.
He says he felt it would be best for Scaramucci to be able to build his own operation "and chart a new way forward".
However, a source told the newspaper that Spicer - and others in the administration - thought hiring Scaramucci, a NY financer, was a "major mistake". Spicer tweeted that it was an "honor & privilege" to serve the president.
A different White House official described Scaramucci to NBC News as a "total professional" with the respect of President Donald Trump. According to the Associated Press two people with knowledge of the decision verified the news.
Sanders has worked a number of political campaigns, including her father's failed 2008 presidential bid, John Boozman's Senate bid in her home state of Arkansas in 2010, and former Minnesota Gov. Tim Pawlenty's failed 2012 presidential bid.
Mr Trump said in a statement read by Ms Sanders that he was "grateful" for Mr Spicer's "work on behalf of my administration and the American people".
Priebus and Spicer spent years working closely together at the Republican National Committee. Reportedly at the meeting, Scaramucci and Spicer also hugged.
