更多有影响力的共和党人转向特朗普

In the US presidential campaign, more influential Republicans are publicly renouncing their party's candidate. This time it's on the grounds that Donald Trump will endanger the country's security. CCTV's Jessica Stone has the story.

Donald Trump's foreign policies continue to cost him support from his own party.

Republican Senator Susan Collins, writing in a Washington newspaper said, if elected, Donald Trump quote: "would make an already perilous world even more so."

Republican senator Susan Collins said, "He simply does not have the restraint and the consideration and the judgement and the knowledge to handle those dangerous events with which presidents are inevitably confronted."

Collins will have plenty of company. In an uNPRecedented public rejection of a presidential nominee by members of his own party, 50 former U.S. national security officials who worked for Republican presidents published an open letter saying a President Trump would be quote, "the most reckless president in American history."

Signers include former directors of the CIA, Department of Homeland Security, even a World Bank president.

Trump says the people who signed that letter are responsible for why "the world is a mess."

He said, "Take a look at what these people, they've been involved with Washington, making decisions, militarily, take a look at what's happened to our country, our military is depleted, our vets aren't taken care of. We can't beat ISIS."

But stumping in the crucial swing-state of Florida, Tuesday, the Democratic presidential candidate, Hillary Clinton tweeted this: "Just imagine Donald Trump in the Oval Office facing a real crisis. We can't afford that kind of risk."

"But it's the revolt among the Republican rank and file that appears to be catching up with Trump. The latest polls shows Clinton has opened up a 10-point lead over Trump. The question is whether Clinton can hold onto it. A British prime minister once quipped that "a week is a long time in politics." There are still three months left until Americans go to the polls," said Jessica Stone from Washington.
