CNN's Jake Tapper questions why John Bolton suddenly pulled from interview. Sarah Sanders responds.

CNN anchor Jake Tapper questioned on Saturday why John Bolton, national security adviser to President Donald Trump, was abruptly pulled from a planned interview for Sunday's episode of "State of the Union."

White House press secretary Sarah Huckabee Sanders provided Tapper with an unequivocal answer.

What did Tapper say?

Tapper announced on Twitter that the White House cancelled Bolton's appearance, noting the testy exchange between CNN's White House senior correspondent Jim Acosta and Trump in England on Friday, seemingly connecting the two events.

During a joint press conference with British Prime Minister Theresa May on Friday, Acosta shouted to the president asking whether he could ask a question "since you attacked CNN." When Trump instead called on Fox News' John Roberts, Acosta asked again.

"No, no," Trump said. "CNN is fake news. I don't take questions from CNN. CNN is fake news! I don't take questions from CNN. John Roberts of Fox. Let's go to a real network."

"Well, we're a real network too, sir," Acosta retorted before Roberts asked his question.

How did Sanders respond?

Sanders confirmed the White House pulled Bolton from Tapper's show because Acosta "disrespected" Trump and May, although she didn't cite Acosta's name specifically.

Sanders said Trump's White House is not in the business of "rewarding bad behavior."
