WASHINGTON – The Democratic-controlled House on Tuesday easily approved a wide-ranging defense policy bill, defying a veto threat from President Donald Trump and setting up a possible showdown with the Republican president in the waning days of his administration.The 335-78 vote in favor of the $731 billion defense measure came hours after Trump renewed his threat to veto the bill unless lawmakers clamp down on social media companies he claims were biased against him during the election.Trump tweeted Tuesday that he will veto "the very weak National Defense Authorization Act,'' or NDAA, unless it repeals so-called Section 230, a part of the communications code that shields Twitter, Facebook and other tech giants from content liability..
