Donald Trump Tuesday tore into rival GOP presidential candidate Ted Cruz, calling him a "liar" and a "nasty" person who nobody likes — and said he is a "lone wolf" like President Barack Obama, only "more strident." "Ted Cruz lies," the front-runner for the party's nomination told MSNBC's "Morning Joe" program. "He is a liar. That's why nobody likes him. That's why the Senate people won't endorse him. He stands in the middle of the Senate floor and can't make a deal with anybody. He's a jerk."
