Tom Harkin's Got a Sign for Trump That's Better Than the Bird

Former Senator Tom Harkin has no words for Donald Trump, but he does have one quick and vivid sign for the GOP candidate.

Harkin -- who spoke at the DNC last week using American Sign Language -- flew into LAX, and we asked him what sign he'd use to describe Donald Trump.

His answer is short and hysterical. Basically, he's saying the Donald is #2 -- as in ... a turd.

Watch and learn a little ASL.
