There was no immediate comment from the administration.
She asked one of the day's key questions about newly appointed acting attorney general Matt Whitaker: "Do you want him to rein in Robert Mueller?" CNN and numerous journalism advocacy groups rejected that assertion and said his pass should be reinstated.
However, there is a very legitimate reason as to why the White House suspended Acosta's credential.
"I was just told to do it", the Secret Service officer said. He started off his exchange with the president by saying that he will "challenge" Trump on his description of the migrant caravan. CNN CEO Jeff Zucker, in a letter to White House chief of staff John Kelly, called Trump's attitude toward CNN a "pattern of targeted harassment".
A 20-year veteran of the White House beat, Ryan pointed out that each president before Trump "understood that reporters were part of the underpinnings of this nation".
Colbert's not the only one who feels Sanders should be fired. When Alcindor asked Trump about Republicans and white nationalists, he called her query "a racist question".
"The White House can not run an orderly and fair press conference when a reporter acts this way, which is neither appropriate nor professional", Sanders said.
CNN's lawsuit, he added, "is critical to preserve the media's ability to ask hard questions and hold the government accountable ..."
President Donald Trump on Friday seemed fretting and fuming at media journalists, instructing them to show more respect in the "sacred" White House.
That assessment gained even more traction Thursday when The Associated Press, citing a video editing expert, reported that a video clip distributed by Sanders on Twitter had been "doctored" to make Acosta's contact with the aide appear more aggressive than it really was.
Despite losing his White House pass, Acosta is expected to travel to Paris this weekend to cover Trump's trip to meet with world leaders. There are many countries that do not allow reporters into the presidential residence in that way. "As visual journalists, we know that manipulating images is manipulating truth", said Whitney Shefte, president of the the White House News Photographers Association.
Sanders hasn't said where the video she posted comes from. Just last June, Acosta shouted questions such as, "did we agree to denuclearize?" to both Trump and the leader of North Korea, Kim Jong Un, during their historic summit.
Acosta's attempts haven't come without criticism and that particular incident earned him a derisive critique from White House advisor Kellyanne Conway. Her question was about the widespread concerns that Trump's rhetoric emboldens white nationalists.
