Trump Picks Up Paul Ryan’s Vote as GOP Coalesces Behind Standard-Bearer

House Speaker Paul D. Ryan announced Thursday that he will vote for presumptive presidential nominee Donald Trump, in another sign Republicans are coalescing behind their party’s standard-bearer ahead of the fall election.

Mr. Ryan, who publicly wrestled for the past month over whether to support Mr. Trump, said in an article published in his hometown newspaper that while the two have their differences, he is confident that the billionaire businessman would help House Republican priorities become law.

“That’s why I’ll be voting for him this fall,” Mr. Ryan, Wisconsin Republican, wrote in an op-ed for the (Janesville) Gazette.

Mr. Ryan had been the highest-ranking Republican official to withhold his support for the presumptive nominee, saying Mr. Trump needed to do more to prove he is conservative enough to helm the party. He also wanted to make sure Mr. Trump wouldn’t ruin House Republicans’ election-year agenda, which they will roll out over the next six weeks.
