WASHINGTON (Reuters) - Paul Ryan, the top elected U.S. Republican, ended a long period of soul-searching and endorsed Donald Trump for president on Thursday, a step toward unifying party loyalists behind the insurgent candidate despite concerns about his candidacy.
Ryan had been a high-profile holdout to supporting Trump for the Nov. 8 presidential election out of concern about the presumptive Republican nominee's bellicose rhetoric and break with party orthodoxy on issues including trade and immigration.
