President Donald Trump's son, Donald Trump Jr., slammed his father's former White House aide and campaign chairman Steve Bannon on Wednesday after outrageous remarks that Bannon made in a book became public.

In the book, Bannon told author Michael Wolff that special counsel Robert Mueller’s investigation would “crack Don Junior like an egg on national TV.” Bannon added that the meeting between Trump Jr. and the Russian lawyer was "treasonous, or unpatriotic, or bad s***.”

Trump Jr. hit back at Bannon following the revelation of his remarks in the book, landing multiple punches on Bannon, who is rapidly becoming an annoyance to the political Right. Trump Jr. wrote in a tweet: "Steve had the honor of working in the White House & serving the country. Unfortunately, he squandered that privilege & turned that opportunity into a nightmare of backstabbing, harassing, leaking, lying & undermining the President. Steve is not a strategist, he is an opportunist."

Trump Jr. also mocked Bannon, pointing out how the comments section on Breitbart's website were filled with angry readers blasting the disgraced Trump official, tweeting: "Wow, Just looked at the comments section on Breitbart. Wow. When Bannon has lost Breitbart, he’s left with . . . umm, nothing."

Trump Jr. also took a swipe at Bannon for damaging Andrew Breitbart's legacy, an observation made by many who knew Breitbart well, writing in a tweet: "Andrew Breitbart would be ashamed of the division and lies Steve Bannon is spreading!"
