TMZ reports:

Lindsey Graham is going high in response to Chelsea Handler going low, after she claimed to out him on Twitter. We got the Senator from South Carolina Friday at Reagan National Airport, and asked him about Handler’s #NationalComingOutDay tweet.

Instead of blasting her — as many others have — Graham insisted Chelsea had every right to say whatever she wants. As he put it, it’s a free country. Graham did tell us, “To the extent that it matters, I’m not gay” — but it was definitely a measured response.
