Former White House chief strategist Stephen Bannon issued a lengthy apology to Donald Trump and his family as several of the president's allies spoke out against an explosive new book that raised doubts about the former real estate developer's fitness for office. The interview ended abruptly with Tapper cutting Miller off as he repeatedly asked to be given three minutes to share his positive impressions of Trump.
"If they were stronger, hopefully, you would not have something like that happen where you can say whatever comes to your head".
Miller praised Trump extensively, saying the "reality" is that the President is a political genius and that Trump's Twitter missive declaring himself a "very stable genius" did not undermine the claim. CNN reported that Trump Jr. was sent the email on September 4, 2016, days before a trove of stolen emails were publicly released.
"That was a snide remark", Miller complained.
With that, Tapper previewed his next block while Miller tried to talk over him.
Miller grew incensed and accused Tapper of being "condescending", and the two started talking over each other. That word means subservient or servile, and Tapper said, "there's one viewer that you care about right now..."
"I'm sure he's watching and he's happy that you said that", Tapper responded.
As for Steve Bannon, Miller said that his role was "greatly exaggerated" within the White House and that "It's tragic and unfortunate that Steve would make these grotesque comments so out of touch with reality and obviously so vindictive".
In the end, Tapper cut the interview short, telling Miller, "I've wasted enough of my viewers' time" before turning to pitch the next segment - all while Miller impotently continued to rant at Tapper from off camera.
The newsman also got into a tussle with Miller over who hired him, suggesting it was Bannon who helped bring the young aide on board.
His comments came as Steve Bannon, the former White House aide who gives damaging quotes in the book, expressed regret at the comments attributed to him.
"Because it's my show, and I don't want to do that", Tapper replied.
Trump's perception was curious, because Miller had not "destroyed" Tapper.
Miller also argued that the president's Saturday tweets, in which he boasted about his "mental stability" and IQ, were helpful in arguing the point that he had the fortitude to do the job.
President Trump's former chief strategist Stephen K. Bannon issued an apologetic statement on January 7, as Trump's anger at his unflattering comments in a new book continues.
