A judge in Washington on Tuesday blocked most of Donald Trump's executive order targeting law firm Susman Godfrey, dealing the Republican U.S. president a new legal setback in its campaign against firms he disfavors.

President Donald Trump signed an executive order Wednesday ordering federal agencies to terminate their contracts with Susman Godfrey LLP, a Houston-based law firm that represented Dominion Voting Systems in its defamation suit against Fox News.
