A Nevada man who was arrested over the weekend with guns at a security checkpoint outside a Donald Trump rally in the southern California desert has filed a lawsuit accusing the sheriff of falsely characterizing his arrest as a thwarted assassination attempt for his own personal gain.

I probably did have deputies that prevented the third assassination attempt,” the Riverside County Sheriff said. Vem Miller has called that claim “ridiculous.”

The Las Vegas man arrested near Donald Trump’s California rally said he is a Trump supporter and alerted police to the guns in his car.
