Trump vs. Sanders debate? The two are tossing idea around

WASHINGTON (AP) — Chances are likely slim, but what about a Donald Trump-Bernie Sanders debate heading into the crucial June 7 California primary?

That possibility surfaced Wednesday, even if in a jocular tone, in an indirect exchange between the Republican billionaire real estate mogul and the senator who Hillary Clinton hasn't been able to bump f-rom the Democratic presidential sweepstakes.

On ABC's "Jimmy Kimmel Live," Trump said he enjoyed watching Clinton's increasingly heated sparring with Sanders.

"I had no idea it was going to be so nasty," said Trump, who said he'd be happy to engage Sanders in a one-on-one debate — as long as significant money goes to c-harity.

Sanders said on Twitter he'd welcome that. "Game on. I look forward to debating Donald Trump in California before the June 7 primary."
