Watch Replay: Sarah Sanders Delivers White House Press Briefing

WASHINGTON, DC — White House Press Secretary Sarah Huckabee Sanders defended the Trump administration and family against attacks from former Chief Strategist Steve Bannon on Wednesday.

Before the briefing, the White House was trying to put out fires started by an explosive report by The Guardian which says that, in a forthcoming book, former White House Chief Strategist Steve Bannon called a meeting between Trump campaign officials and Russians "treasonous."

Trump denounced his former aide swiftly, saying, "When he was fired, he not only lost his job, he lost his mind."

Sanders also repudiated the book by Michael Wolff.

“This book is filled with false and misleading accounts from individuals who have no access or influence with the White House," she said. "Participating in a book that can only be described as trashy tabloid fiction exposes their sad desperate attempts at relevancy.”

When asked about the Bannon's comments during the White House press briefing, she referred back to the president's statement. She also downplayed Bannon's relationship with the president and Wolff's access to White House sources. She added that she was personally surprised by many of Wolff's claims, which did not reflect her experience with the president.

Sanders also rejected charges that Trump's recent comments toward the leader of North Korea about nuclear war demonstrated mental unfitness for the presidency.

"North Korean Leader Kim Jong Un just stated that the 'Nuclear Button is on his desk at all times,'" he wrote. "Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!"

Sanders said that Americans should worry about Kim Jong-un's mental wellness, not Trump's. She confirmed that the president does not have an actual "button" to launch nuclear weapons. The button was simply a metaphor for the size of the U.S. nuclear arsenal.
