Donald Trump has fired the acting US attorney general, after she questioned the legality of his immigration ban.
Sally Yates, who had been appointed under Barack Obama, earlier ordered justice department lawyers not to enforce the president’s executive order.
In a statement, the White House said Ms Yates had “betrayed” the department.
Dana Boente, US attorney for the Eastern District of Virginia, replaces her as acting attorney general.
Mr Trump’s order temporarily banned nationals from seven Muslim-majority countries from entering the US, and sparked street protests in the US and abroad.
