From the Daily Caller:

Kentucky Republican Sen. Rand Paul’s press secretary Moira Bagley tweeted on Monday that Transportation Security Administration officials were detaining her boss in Nashville, Tenn.

“Just got a call from @senrandpaul,” Bagley tweeted at about 10 a.m. on Monday. “He’s currently being detained by TSA in Nashville.”

Texas Congressman and current Republican presidential candidate Ron Paul – Sen. Rand Paul’s father – placed a post on Facebook about the news as well. “My son Rand is currently being detained by the TSA at the Nashville Airport,” Ron Paul posted. “I’ll share more details as the situation unfolds.”

Ron Paul adds, via Twitter, that the TSA detained his son “for refusing full body pat-down after anomaly in body scanner.”

I’m guessing that Rand Paul was en route to Washington for the Congressional session, in which case the TSA (and therefore the administration) have just violated the Speech and Debate Clause in the Constitution.
