Bob Woodward blasted as "garbage" an unsubstantiated dossier released by U.S. intelligence agencies that alleges deep ties between President-elect Donald Trump and Moscow.

In an interview on "Fox News Sunday," the celebrated Washington Post editor said he sided with Trump in his fight with intel agencies on the salacious document.

"I’ve lived in this world for 45 years where you get things and people make allegations," he added. "That is a garbage document."

"In Trump’s mind, he knows the old adage, 'once a CIA man, always a CIA man,' and no one came out and said those people shouldn’t be saying those things," Woodward added. "So act two is the briefing when this dossier is put out."
