Scaramucci, 53, who was appointed as the White House Director of Communications only 10 days ago and was reporting directly to the president, was in the news for the past few days, especially for the "unparliamentary" language used by him against his White House colleagues.
In an interview last week, the former Wall Street financier used unparliamentary language against his White House colleagues and threatened to fire everyone from the White House who leaked information.
Scaramucci was fired hours after John Kelly, 67, a retired marine general, took over as the new White House chief of staff, replacing Reince Priebus who was fired after continued feud among the senior White House staffers came out in the open.
In the last 10 days, Trump has fired three of his top officials. It first began with his Press Secretary Sean Spicer, followed by Priebus and now Scaramucci, who probably had the shortest stint as the White House Director of Communications.
Sanders said Trump has given full authority to Kelly, and he'll make determinations inside the White House.
"General Kelly I think will bring new structure to the White House and discipline and strength. We are all really excited to work with him," she said.
