President Donald Trump hyped a book full of embarrassing revelations about himself in a Saturday morning tweet.

"Congratulations to two great and hardworking guys, Corey Lewandowski and David Bossie, on the success of their just out book, 'Let Trump Be Trump.' Finally people with real knowledge are writing about our wonderful and exciting campaign!" Trump posted.

The book explains how Trump drinks up to a dozen Diet Cokes a day, loves to eat fast food from McDonald's or Kentucky Fried Chicken and has wild mood swings.

“Watching cable, [Trump] shares thoughts with anyone in the room, even the household staff he summons via a button for lunch or one of the dozen Diet Cokes he consumes each day,” the book explained.

The poor diet may exacerbate Trump's mood swings.

“Several advisers said the president may curse them for a minor transgression…then make amiable small talk with the same person minutes later," the book noted.

The presidential product plug did not reveal whether Trump had read the book. One of the revelations contained within is how little the commander in chief reads.
