Gov. Scott Walker says House Speaker Paul Ryan doesn't need defending following an appearance by Republican presidential nominee Donald Trump in Wisconsin.
At one point during Trump's appearance in Green Bay Monday night, some in the crowd joined in a chant against Ryan, who's from Janesville. During a stop in Kenosha Tuesday, Walker said Ryan got 84 percent of the primary vote and doesn't need defending.
As for Trump's claim that voter fraud is a significant threat to the integrity of the U.S. electoral system, Walker says "it's easy to vote, but hard to cheat" in Wisconsin because of the law that requires voters to show photo ID at the polls.
Walker seems unlikely to appear with Trump in the weeks ahead, saying he's focused on candidates in Wisconsin and Republican governors.
