Exclusive TMZ.com Congressman Adam Schiff is not only Donald Trump‘s arch-enemy, he’s also now a celebrity. The Democrat from Burbank was flanked by security Friday afternoon as he showed up to the Coffee Bean on the Sunset Strip. When he left the java joint, he mugged with a few supporters who recognized him and asked for selfies. Schiff obliged. There was a funny moment. An eyewitness tells us at one point Schiff gave his coffee to a security dude while he took a selfie, and the hired muscle didn’t look too happy. Schiff has clearly gotten under Trump’s skin and the 2 have gone back and forth on social media trading insults.
