Trump interrupted Acosta. "I'm not concerned about anything with the Russian investigation because it's a hoax".
Earlier in the day, President Donald Trump called Acosta a "rude, awful person" during a press conference and tried to cut off his questioning. "This conduct is absolutely unacceptable", is, however, the explanation given by Sanders.
The decision comes after a tense standoff between Acosta and President Donald Trump during a press conference on Wednesday. When Acosta tried to follow up with another question, Trump said, "That's enough!" and a female White House aide unsuccessfully tried to grab the microphone from Acosta.
A staff member tried to take his microphone during the exchange. She did not say to whom she was referring, but the implication was that it was Acosta.
"CNN should be ashamed of itself, having you working for them". Go ahead. You're a very rude person the way you treat Sarah Huckabee is frightful and the way you treat other people are disgusting.
CNN took to Twitter calling Trump's attacks on the media as "un-American".
Later the White House said it was suspending the correspondent's pass until further notice.
"I do think, Anderson, that this is a test for all of us", he said.
Trump also barked at April Ryan, another frequent White House critic, repeatedly telling her to sit down and not speak out of turn.
Acosta continued to ask questions, including whether Trump was "concerned" about potential indictments coming from the Mueller probe. Those were reporters working with CNN, NBC, other networks.
Mr Acosta called Ms Sanders' assertion that he placed his hands on the woman "a lie".
Trump began taking questions and called on Acosta, who tried to ask about the president's characterization of a migrant caravan of roughly 4,000 Central American immigrants who are walking through Mexico to claim asylum in the U.S.
Acosta was stopped by the Secret Service from entering the White House at about 7 pm. This unprecedented decision is a threat to our democracy and the country deserves better. The White House has accused him of provoking confrontations, and he, in turn, has become a favorite target of insults lobbed by Trump's supporters, particularly during the president's raucous rallies. The CNN reporter has made a name for himself by asking combative questions of Trump and other administration officials.
