LOUISVILLE, Ky. — As he seeks to unite a fractured party, Donald Trump rallied one of the Republican Party’s most faithful constituencies on Friday, telling an audience of thousands of gun owners at the National Rifle Association’s annual convention that he will be a faithful defender of the right to bear arms if he wins the presidency. The promise won Trump the NRA’s endorsement, and the group’s leaders repeatedly urged conservatives to unite behind the real estate mogul as they prepare to take on a mutual foe: likely Democratic nominee Hillary Clinton. In what was his second appearance before the NRA membership, Trump slammed Clinton as the most “anti-gun” and “most anti-Second Amendment” candidate ever to seek the presidency.
