In a one-on-one interview with ABC's George Stephanopoulos, 2016 GOP candidate Ted Cruz said that rival Donald Trump is "rattled"  by Cruz's surge in the polls which is why he is obsessively attacks the Texas senator at his rallies.

The cold war between the New York billionaire and the Texas senator has grown heated since the last GOP debate after Cruz attacked Trump over his "New York values," leading Trump to hit back by invoking the bravery of New York residents in the wake of the 9/11 tragedy.

Since that time, Trump has made Cruz the main focus of his attacks on the campaign trail and on cable talk shows, pointing out that Cruz is "nasty" and highly disliked by his GOP peers.

Speaking with Stephanopoulos over the weekend, Trump ripped into Cruz, saying: “The truth is he’s a nasty guy, nobody likes him. Nobody in Congress likes him. He’s a very — he’s got a edge that’s not good. You can’t make deals with people like that. It’s not a good thing for the country. Very nasty guy.”

Speaking with Stephanopoulos, Cruz said his rise in the polls has got Trump worried.

“Donald is getting rattled. I mean, it’s amazing. At every event, instead of actually talking about what he wants to do for the country, he just kind of stands up there and attacks me the whole time,” Cruz explained.

Cruz's comments about Trump, who has been leading in the polls for months, comes on a day when the Republican establishment, led by the National Review, have launched a full-on assault against Trump out of fears that he is destroying not just the GOP, but the conservative movement  in the U.S.
