The White House is suspending the credentials of a CNN journalist hours after he was insulted by US President Donald Trump.
Press secretary Sarah Sanders says a reporter’s access was suspended because he put “his hands on a young woman”.
Mr Acosta, chief White House correspondent for CNN, was called a “rude, terrible person” by Mr Trump at a press conference on Wednesday.
A staff member struggled with him for his microphone during the exchange.
In a tweet Mr Acosta says he was stopped by the Secret Service when he tried to re-enter the White House on Wednesday evening.
Ms Sanders, in a tweeted statement, said the White House would “never tolerate a reporter placing his hands on a young woman just trying to do her job”.
“As a result of today’s incident, the White House is suspending the hard pass of the reporter involved until further notice.”
