GOP presidential candidates weigh in on January debate participation

There are expected to be three Republican presidential debates in January, but which of the major candidates will actually show up, or even make the stages, is far from clear at this point. 

A CNN debate will be hosted in Iowa, which has the first Republican caucus, while CNN and ABC/WMUR are set to have separate debates in New Hampshire, which is home to the first presidential primary. The debates give the candidates trailing former president Donald Trump by large margins a chance to make their pitch on a national stage before voters head to the polls. 

Candidates' ability to participate will hinge on meeting requirements laid out by each organization hosting the debates. But as of Friday evening, Vivek Ramaswamy's campaign was the only one to tell CBS News that the Ohio entrepreneur intends to be at each of the upcoming trio of debates, which were announced earlier this week.
