PORTSMOUTH, N.H. — Republican presidential candidate Donald Trump tore into GOP rival Sen. Ted Cruz (Tex.) over his failure to properly disclose two million-dollar loans that helped fund his 2012 U.S. Senate campaign, calling him “hypocritical” during a speech here in Portsmouth and accusing him of being controlled by large banks.

“How do you control … these big powerful banks, you’re a senator and yet you owe them money with a personal guarantee,” Trump told a crowd of about 500 people. “So he obviously didn’t want the voters to know that he is totally control, lock stop and barrel, by Citibank and Goldman Sachs. And I think that’s very hypocritical.”

Trump said that he liked Cruz and believed him to be a “nice guy,” but “as it turned out, he finally went off the wagon a little bit and went a little bit crazy.”

“He talks about he’s going to be Robin Hood … then you find out that on his personal disclosure form he didn’t disclose that he’s borrowing a lot of money," Trump said.

Cruz was in Portsmouth attending the "No BS Backyard BBQ" event series sponsored by former U.S. senator Scott Brown. Cruz will attend the last event in the series on Tuesday.

Cruz and Trump are caught in an escalating war of words as they battle for support in the early voting states. With the Feb. 1 Iowa caucuses just two weeks ago, each candidate is trying to energize supporter in the Hawkeye State while also courting undecided voters torn between the two.

Trump, who published a torrent of tweets criticizing Cruz Saturday morning, also knocked the senator for comments he made disparaging “New York values.” In perhaps his strongest moment at any GOP debate, Trump unloaded on Cruz Thursday by making a poignant appeal to the strength New Yorkers showed following the Sept. 11 terrorist attacks.

“They ran into the buildings and they were running up the stairs and they knew it could collapse,” Trump said while talking about first-responders on the ground immediately following the attack.

Trump said that fire departments from all over the country mobilized to help New York in the following days, including units from Iowa.

“And Ted Cruz criticized New York and the people of New York? It’s a disgrace. I think it’s a total disgrace. A total disgrace,” he told the crowd, many of whom nodded in agreement. “I thought what he said was very, very sad.”
