I would suggest all you Trump supporters who felt this was a threat, to call the Burbank Police Department and press charges.
Lindsey Graham made two jokes about killing Ted Cruz, and Ted uses them in his stump speech and at AIPAC.
Politicians and their supporters need to have a little thicker skin.
I imagine some Trump supporters have already reported this as a threat. Their names have been added to the list of possibly mental unstable people who need to be monitored.
