President Barack Obama laughed off protesters wearing T-shirts promoting right-wing conspiracy site InfoWars and shouting “Bill Clinton is a rapist” during a Tuesday campaign rally for Hillary Clinton.

"Those folks are auditioning for a reality show," Obama told a crowd in Greensboro, North Carolina, where his speech was repeatedly interrupted by hecklers.

InfoWars host Alex Jones, an avowed supporter of Donald Trump who recently claimed the Democratic nominee was “demon-possessed”, on Friday announced a contest for listeners who promoted the message that Bill Clinton raped women. Jones offered $1,000 to supporters who made it on TV for at least five seconds wearing “Bill Clinton rape” shirts and $5,000 to those who can be heard shouting “Bill Clinton is a rapist” while wearing the shirts.

His supporters have heeded the call, popping up at a Clinton rally in Miami and an event hosted by Bill Clinton in Wisconsin over the weekend.
