Okay, maybe two douchebags:

Kids were murdered in a shooting at Santa Fe High School today. But don’t worry, the Republican Congress will send their thoughts and prayers. They won’t actually do anything to prevent it from happening again. But thankfully we have their thoughts and prayers. Pathetic traitors.
