WASHINGTON: Hillary Clinton said on Monday she has received private messages from foreign leaders asking to endorse her candidacy in hopes of defeating Republican front-runner Donald Trump.

Clinton refused to name the dignitaries, though she says she told them that the election must be decided by Americans. But, she said, her experience as secretary of state will offer a powerful contrast with Trump, should they face off in the general election.

“I believe that I will have an opportunity to really focus in on how dangerous a Donald Trump presidency would be for our standing, for our safety and for the peace of the world,” she said.

Ted Cruz said on Monday if Trump were to “go out on Fifth Avenue and shoot somebody,” he would not support him as the party’s nominee.

But speaking at a press conference in Rockford, Illinois, Cruz refused to acknowledge the possibility that Trump would win the nomination, with just one day to go until a crucial cluster of winner-take-all primaries.

Instead, Cruz offered his own worst-case scenarios for what a Trump nomination would do to the party and the country.

“We elect Hillary Clinton and we destroy the country if Trump is the nominee,” he said. He repeatedly noting that he has won more primaries than anyone other than Trump and so he is best positioned to beat him to the nomination.

Also on Monday, former Republican presidential candidate Ben Carson avoided questions over whether Trump is fit to lead the country after making comments viewed as encouraging violence at his rallies.

Speaking on NBC’s “Today,” Carson, who endorsed Trump last week, acknowledged that he might not use the same rhetoric that Trump uses at his rallies, but emphasized that Trump is a different person off-stage and should not be discounted.
