Donald Trump stooped to a new low in his feud with Sen. Ted Cruz (R-Texas) over their wives, retweeting an image late Wednesday night comparing the physical appearance of his wife, Melania, to that of Cruz's wife, Heidi:

Cruz responded in less than an hour:

Wednesday night's tweets are just the latest in an ongoing battle between the top two Republican presidential candidates. Trump stirred up trouble Tuesday when he threatened to "spill the beans" on Cruz's wife because he says Cruz "used a picture of Melania from a G.Q. shoot in his ad."

Cruz has reminded Trump that the ad was not from him, but from a super PAC, and that attacking women only makes him "classless" and a "coward." Heidi Cruz's response: Trump's statements often "have no basis in reality."
