Republican presidential front-runner Donald TrumpDonald John TrumpAccuser says Trump should be afraid of the truth Woman behind pro-Trump Facebook page denies being influenced by Russians Shulkin says he has White House approval to root out 'subversion' at VA MORE says fellow GOP primary candidate Chris Christie called him after Tuesday night’s New Hampshire primary to have a “long talk.”

Asked whether he would seek Christie’s endorsement if the New Jersey governor drops out of the race, Trump praised Christie for his performance at last week’s GOP primary debate.

“I think that Chris did an amazing job in terms of the debate, as a prosecutor, and he’s a friend of mine,” Trump said early Wednesday on MSNBC’s “Morning Joe.”

“And he actually called me last night, and we had a long talk, and he’s a little disappointed because he really did do a great job, he did an amazing job during that debate,” he added.

Christie had a disappointing primary night, finishing in sixth place in the Granite State after he appeared to be building momentum with successful attacks on primary rival Marco RubioMarco Antonio RubioColbert: Students taking action on gun violence 'give me hope' Lawmakers feel pressure on guns Florida lawmaker's aide fired after claiming shooting survivors were 'actors' MORE.

The governor said he would return home to rethink his campaign.

Trump said he hopes Rubio, who struggled to a fifth place finish in the New Hampshire primary, can turn his campaign around.

“I was witness to it, because I was standing next to Marco, who I like very much, and, you know, it was a strange kind of situation going on there,” he said. “It was a little bit strange. And Marco understands that, and he’ll be able to fix it I hope.”
