Republican presidential candidate Marco Rubio lost his voice on Monday ahead of a campaign event.
Rubio was introduced by South Carolina Gov. Nikki Haley, who endorsed him earlier this month, at the event. Haley told the crowd that Rubio had lost his voice.

An an earlier event in Tennessee, Rubio vowed to sacrifice his voice for the future of the country and to beat rival Donald Trump.
“We’ve been working hard for you,” he said, according to Breitbart News.
“And if it means by the end of tonight, I don’t have a voice and I have to whisper how strongly I feel about the future of this country, then I’m willing to do it.
“Our Veterans and so many others have given up way much more than just their voice for just one day,” he added.
Rubio and Trump have engaged in personal attacks in recent days, mocking each others appearance and background.
