A federal judge in Washington has ordered the Trump administration to immediately return the White House press credentials of CNN reporter Jim Acosta.
US District Court Judge Timothy Kelly announced his decision on Friday.
CNN had asked that Mr Acosta's credentials be returned while a lawsuit over their revocation goes forward.
The network's chief White House correspondent has clashed repeatedly with Mr Trump and press secretary Sarah Huckabee Sanders in briefings over the last two years, and the White House pulled his credentials last week following a combative press conference in which he clashed with the president.
'This is a lie'
After the confrontation, White House press secretary Sarah Sanders released a statement accusing Mr Acosta of "placing his hands on a young woman just trying to do her job as a White House intern," calling it "absolutely unacceptable".
The interaction between Mr Acosta and the intern was brief, and Mr Acosta appeared to brush her arm as she reached for the microphone and he tried to hold on to it. "Pardon me, ma'am," he told her.
Mr Acosta tweeted that Ms Sanders's statement that he put his hands on the aide was "a lie".
Journalists assigned to cover the White House apply for passes that allow them daily access to press areas in the West Wing.
White House staff decide whether journalists are eligible, though the Secret Service determines whether their applications are approved.
The judge was a Trump appointee.
