Sean Spicer, White House press secretary, resigned today after meeting with President Trump in protest of the appointment of Wall Street financier Anthony Scaramucci as communications director.

The former spokesperson for the Republican National Committee reportedly refused Trump's offer to remain on staff because he believes the hiring of the ex-hedge fund executive is a huge mistake.

Spicer's departure's cast a cloud over the future of Trump chief of staff, Reince Priebus, who chaired the RNC and opposed the outreach to Scaramucci, who is known as "Mooch."

A major Republican donor, Scaramucci is a frequent guest on Fox News and is a friend of Sean Hannity.

"Anthony Scaramucci is somebody who has been an incredible asset to President Trump all during the campaign, the transition, and now he is one of the killers on TV who goes out there, thinks the president is being treated very unfairly, and we don’t get any of the economic news out there, even though our press and communications shop tries,” Kellyanne Conway told Fox today.

After backing Scott Walker and Jeb Bush during the GOP primary season, Scaramucci changed his allegiance to Trump. He recently sold his stake in SkyBridge Capital and was working at the Export-Import Bank.

Scaramucci takes over for the recently resigned Michael Dubke. He named Sarah Huckabee Sanders, who was filling in for Spicer, new White House press secretary.
