Story highlights Clinton has long used Trump's presidential bid as a laugh line in her otherwise wonky stump speech

Clinton has responded bluntly to Trump's proposal to ban Muslims from entering the U.S.

New York (CNN) Hillary Clinton used to think Donald Trump's large-than-life presidential campaign was something to laugh about. But that changed after his recent comments about Muslims, she said Thursday.

"I have to say Seth, I no longer think he is funny," she said during an interview on NBC's "Late Night with Seth Meyers" that was set to air early Friday morning. "I think for weeks you and everybody else were just bringing folks to hysterical laughter, but now he has gone way over the line. And what he is saying now is not only shameful and wrong, it is dangerous."

Trump released a written statement earlier this week calling for the U.S. to ban Muslims from entering the country. He has forcefully defended the proposal despite widespread criticism from both Democrats and Republicans.

Clinton has responded bluntly to Trump's proposal, but has also tried to score political points by linking the broader Republican Party -- particularly those Republicans running for president -- with the bombastic front-runner.

"Some of his Republican rivals are saying that his latest comments have gone too far. But the truth is many of them have said extreme things about Muslims. Their language may be more veiled than Trump's but their ideas aren't so different," Clinton said during a town hall in New Hampshire on Tuesday.
