Sean Spicer says Trump can fire Mueller: 'You serve at the pleasure of the president -- that is a fact'

During a Monday press conference that media outlets were banned from airing, White House Press Secretary Sean Spicer announced that the president's was sending "thoughts and prayers" to the victims of an alleged terrorist attack in London and to the families of seven dead U.S. sailors.

Spicer began the blacked out press conference by acknowledging the seven sailors who were recently killed USS Fitzgerald and the victims of an attack outside a mosque in London that left one dead.

“The president has been made aware of the attack in London," Spicer reportedly said.

Spicer defended the ban on broadcasting the briefing by noting that President Donald Trump had already appeared on camera on Monday for several minutes, although he took no questions.

CNN's Sarah Murray pointed out that Trump has not personally addressed the London attack.

Spicer also said that the president had confidence in all the members of the Justice Department, including Special Counsel Robert Mueller, who is reportedly investigating the president for obstruction of justice.

According to the press secretary, it is "possible" that Trump may reveal by "the end of the week" if there are recordings of his conversations with fired FBI Director James Comey. Spicer insisted, however, that the Trump has the power to fire Mueller if necessary.

"If you serve at the pleasure of the president, you serve at the pleasure of the president," he said. "That is a fact."

On the topic of climate change, Spicer said that he had been too busy to ask the president if he believes the phenomenon is a hoax.
