Stone, who spoke to The Hill as he left the Quicken Loans Arena, warned that the Texas senator's public unwillingness to back Trump would come back to haunt him.

"By Ted Cruz not supporting the nominee, he's exempted himself from real conservatives," he said. "No voter gives a crap about what Ted Cruz does. The only person this hurts is Ted Cruz." He continued to excoriate Cruz, whom delegates showered with boos as they realized he wasn't going to endorse Trump during his speech to the convention.
