A U.S. judge has agreed to temporarily block implementation of President Donald Trump's executive order to strip security clearances and take other actions against prominent law firm Perkins Coie over its policies promoting workforce diversity and its work for his 2016 election rival Hillary Clinton.

A judge imposed a temporary restraining order against the Trump administration, barring it from enforcing parts of an executive order penalizing a law firm.

Trump says he's suspending security clearances of lawyers at Perkins Coie, which was involved in launching oppo research during the 2016 campaign into any ties between Trump and Russia.
