— -- 1. John Kasich Declines to Say Whether Donald Trump Is Fit to Be President

Ohio Gov. John Kasich refused to say whether presidential nominee rival Donald Trump was fit to be president a day after criticizing the party's front-runner over recent violence at his rallies.

"You’re not going to get me to answer a yes-or-no question," Kasich said. "I hope he’s going to change his rhetoric and bring people together."

Kasich criticized Trump Saturday for creating a "toxic environment" that has led to violence at some of his rallies. He had previously pledged to support Trump if the New York real estate mogul were to win the nomination, but said Sunday that "nothing's 100 percent."

"Sometimes it’s really tough," Kasich added. "I hope to be able to support whoever the nominee is."

2. Clinton Questions Sanders' Health Care Work in '90s, Despite Video Showing Them Together

Hillary Clinton Saturday suggested that campaign rival Bernie Sanders was not involved with her fight for universal health care in the 1990s, despite video footage from the time that appears to show otherwise.

“I always get a little chuckle when I hear my opponent talking about doing it,” she said at a rally today in St. Louis, referring to universal health care. “Well, I don’t know where he was when I was trying to get health care in ’93 and ’94, standing up against the insurance companies, standing up against the drug companies.”

The remark raised eyebrows after a Sanders staffer immediately tweeted out video from 1993 of the Vermont senator standing directly behind the then-first lady during a news conference about health care. In the video, Clinton thanks Sanders for being there. “I’m grateful that congressman Sanders would join us today from Vermont,” she said.
