More unity in the Republican party over Donald Trump as the House Speaker says that he'll vote for the presumptive Republican nominee.

FOX's Jon Decker has more from the White House:

House Speaker Paul Ryan said on Twitter that he'll be voting for Donald Trump this fall and that he's confident he will turn the House Republican's agenda into laws.

Further explaining why he's endorsing Trump in his hometown newspaper, Speaker Ryan wrote that although he and Trump have differences, on the issues that make up the Republican agenda, he and Trump have more common ground than disagreement.

Ryan said that from the start, his goal has been to unite the party so it can win in the fall.
