White House: Wolff's book contains "numerous falsehoods"

• The West Wing cell phone ban has nothing to do with the publication of excerpts from the new book, Sanders told reporters.
• Sanders called Wolff's book "some trash from an author no one has ever heard of before today."
• The White House denied "at least two dozen" requests from Wolff to sit down with the president for his book, per Sanders.
• Breitbart should "consider" parting ways with Bannon, Sanders said.
• "The president absolutely believes in the First Amendment, but as we've said before, the president also believes in making sure that information is accurate before pushing it out as fact," Sanders said.
• Is Gary Cohn on his way out? Sanders has "no reason to know of any personnel change."

One more thing: The briefing opened with a video message from Trump — unusual, as he presumably could have appeared in person — touting the tax cuts law.
