MADISON, Wis. — Democrats are ripping Republican U.S. Sen. Ron Johnson for supporting Donald Trump despite Trump’s predatory remarks about women and allegations he has sexually assaulted a number of women.

Johnson is locked in a tight race with Democrat Russ Feingold. Johnson said Friday that he supports Trump on a number of issues. He added, however, that he wasn’t going “to defend the indefensible.”

State Rep. Chris Taylor, a Madison Democrat, said on a conference call with reporters Monday that Johnson needs to explain why he’s still supporting Trump. She accused Johnson of sending a message that women aren’t important.

Johnson campaign spokesman Brian Reisinger said Johnson has called Trump’s remarks indefensible and it’s up to Trump to address the assault allegations. Trump has denied the accusations.
