READ MOREThe move came just hours after Acosta, CNN's chief White House correspondent, drew the ire of President Donald Trump and his allies by asking multiple questions at a post-midterms news conference. Trump insulted Acosta and called him a "terrible" person, CNN reported.
White House Press Secretary Sarah Sanders announced in a statement that Acosta would be stripped of what's known as a "hard pass," which gives him access to the White House grounds.
CNN said in a statement that Acosta has the network's full support.
The revocation of his pass "was done in retaliation for his challenging questions at today's press conference," the statement said.
"In an explanation, Press Secretary Sarah Sanders lied. She provided fraudulent accusations and cited an incident that never happened. This unprecedented decision is a threat to our democracy and the country deserves better. Jim Acosta has our full support."
In the 7 p.m. hour on Wednesday, Acosta was stopped at the White House's Pennsylvania Avenue gate where reporters usually enter. He was heading back to the White House for a live shot on "Anderson Cooper 360."
"I've just been denied entrance to the WH," Acosta tweeted. "Secret Service just informed me I cannot enter the WH grounds for my 8pm hit." Acosta posted a video of a Secret Service officer removing his pass. "I was just told to do it," the officer said on the recording. "I am now giving my hard pass to the Secret Service," Acosta said. ■
