President Donald Trump (L-R), is joined by Chief of Staff Reince Priebus, Vice President Mike Pence, senior advisor Steve Bannon, Communications Director Sean Spicer and National Security Advisor Michael Flynn, as he speaks by phone with Russia's President Vladimir Putin in the Oval Office at the White House in Washington, U.S., January 28, 2017.

Not unexpectedly, the president immediately responded with a similar level of vitriol to Bannon's comments in the book.

The first week of the new year for President Donald Trump 's administration got off to an explosive start Wednesday after excerpts from a forthcoming book on the early days of the Trump presidential candidacy produced shocking allegations from former campaign CEO Steve Bannon.

Also, not to be overlooked amid the turmoil, Trump's former campaign chairman Paul Manafort sued special counsel Robert Mueller, Deputy Attorney General Rod Rosenstein and the Department of Justice in U.S. federal court alleging that the investigation has strayed beyond the scope of the original probe Mueller was authorized to pursue.
