Rush Limbaugh Jokes About A Military Coup

From Talkingpointsmemo:

Rush Limbaugh may have crossed another line today in his anti-Obama rhetoric -- openly joking (at least, we hope he's joking) about a military coup.

Limbaugh noted that President Obama will be delivering his upcoming speech on Afghanistan, from the United States Military Academy at West Point.

"My question is: Will they detain him?" said Limbaugh. "Hopefully."

Can we call it treason yet?
