According to The Hill:
“Ted Cruz on Monday faced off against Donald Trump supporters who crashed an event in Indiana, where the GOP hopeful is desperately working to upset the front-runner and keep his White House dreams alive.
Protestors started chanting “Do the math” during Cruz’s stop in Marion, Ind., prompting the Texas senator to walk up to to a demonstrator holding a Trump campaign sign.The man, who refused to give his name to reporters but said he had come from Ohio, interrupted Cruz and repeatedly called him “Lyin’ Ted,” Trump’s favorite nickname for his rival.
“With all respect, Donald Trump is deceiving you, playing you for a chump,” Cruz said.”
