Despite Sanders' efforts to downplay the bombshell op-ed, Cooper said the "dust hasn't even begun to settle" as it is "not every day an administration official writes 'the root of the problem is the president's amorality'".
Camp David is a retreat of the U.S. President, 100 km northeast of Washington, in Maryland.
Trump jumps from topic to topic, talking about the real "Russia story" involving his Democratic opponent, Hillary Clinton; the deadly Niger ambush on American soldiers; and economic gains.
Bob Woodward's book detailing the chaotic atmosphere in Trump's White House is officially a hit.
Case in point, one excerpt reveals the newly appointed National Economic Council director Gary Cohn's "I've had a huge mistake" moment in his first meeting with then president-elect Trump. "A source tells us he [Trump] shouted out 'Bring back Hope Hicks!' Apparently, he preferred her response to ["Fire and Fury" author] Michael Wolff", said Blackwell.
And Woodward, the victor of two Pulitzer prizes, said, "I'm not".
In a series of tweets, Trump has called the book "total fiction", "boring" and "untrue". During the lengthy interview, Colbert asked what in Woodward's research gave him the most fear? The Trump White House has shocked him more than any of the eight others he's covered, he added, because Trump fundamentally doesn't understand that national security is more than just the US military.

The Ryder Cup matches will be played September 28-30 at the Albatros Course of Le Golf National , just outside of Paris. Keegan Bradley won the tournament in a playoff and also was thought to be under consideration.
Later on during the interview, Woodward put Guthrie on the spot, when she questioned him about specific portions of his book.
Cohn was "astounded at Trump's lack of basic understanding", Woodward writes.
Pressed on whether Trump can win a credibility battle with the Pulitzer victor who helped expose President Richard Nixon's Watergate-era transgressions, Sanders pointed to "actual, on record" accounts from White House staffers, again pointing to Mattis and Kelly, "not disgruntled former employees".
President Trump also tweeted that Woodward's book is "a joke" and "another assault" against him.
But can he say whether his current work will play a similar role in Trump's political future?
"And that's how you end the book", Colbert said.
"There's a war on truth", Woodward's answered, echoing what we've heard before. Also, Woodward steers clear of Trump's controversial decision to move the US embassy to Jerusalem, thanks in part to the efforts of his ardently pro-Israel son-in-law Jared Kushner.
"Fear" is scheduled for release Tuesday morning.
