Republican presidential candidate Ted Cruz is intensifying his attacks on chief rival Donald Trump, calling him a phony and liar who is betraying conservative voters.

Over the course of Saturday at campaign stops in both Pennsylvania and Indiana, Cruz coined new punchlines attacking Trump, calling him everything from a master illusionist like Houdini to a man who campaigns like Mick Jagger parachuting into a rock concert concert to someone who should consider writing "The Art of The Betrayal."

Speaking from the bed of a pickup truck in the parking lot of a Plainfield, Indiana, diner, Cruz energized a crowd of supporters by calling Trump "crazy Donald" and a "phony Donald."

"He is laughing at the American people and pretending to be something he's not," Cruz told reporters after the rally. "If you want to be elected president, you need to show the humility to come and ask for the support of the people -- not parachute in like Mick Jagger, give some disjointed speech in a football stadium and then fly out on your jet back to New York City.

"We've had enough politicians who are pretenders," he said.

Cruz also bashed Trump for his opposition to the North Carolina bathroom bill.

"So let me make things real simple, even if Donald Trump dresses up as Hillary Clinton, he shouldn’t be using the girl’s restroom,” said Cruz at a rally in Lebanon, Indiana.

Cruz then laughed, apologizing to the audience for giving them the image of "Donald in a bright blue pantsuit."

"But let me just say to Jimmy Fallon and 'The Tonight Show,' please give us that image," Cruz said.
