"Sad day in America:" Republican Wisconsin Assembly speaker calls out Donald Trump

MADISON — Republican Wisconsin Assembly Speaker Robin Vos says he is embarrassed about Donald Trump being the GOP presidential nominee, calling it a "sad day in America."

But he tells The Associated Press that he's not rescinding his support for Trump because he says Democrat Hillary Clinton would be worse.

Vos wrote a column Friday in advance of a Trump rally in Green Bay. He calls Trump out for saying "stupid things" and for praising House Speaker Paul Ryan's primary opponent. Trump also said this week he was not ready to endorse Ryan.

Vos says "we are Ryan Republicans here in Wisconsin, not Trump Republicans."

In the interview, Vos says Trump needs to apologize for his comments about Ryan.

None of the top-ranking Wisconsin Republicans are going to the Trump event.
