Donald Trump isn't worried about Marco Rubio. In fact, the Florida senator and Republican presidential rival means nothing to him, Trump's special counsel and spokesman Michael Cohen said Friday.

"He's still eight times higher than Marco Rubio. He doesn't think about Marco Rubio. Marco Rubio doesn't mean anything to him. And as far as foreign policy, what gives Marco Rubio the right to talk about foreign policy?" Cohen said in an interview on CNN's "New Day" with Alisyn Camerota about the latest polls.

Rubio is on the Senate Foreign Relations Committee, Camerota responded.

"And look at where we're at as far as this country is concerned. We are a disaster in this country as far as foreign policy. We're not respected by any country in this world," Cohen said. "This is not a man who belongs in the White House."

Following numerous attacks from Trump on his age and his very being in the race, Rubio jabbed back on Thursday, calling the billionaire real estate mogul "touchy and insecure" and "exposed" on not having positions on the issues.

Asked whether Trump has hit a ceiling, as some pundits have predicted, Cohen slammed those assertions.

"They said that when he hit 18 percent and they said it again when he hit 20 and then 25. They called it the summer fling. Donald Trump is the all-American. He is the man that will make America great again. He has awoken the silent majority, and they're not backing down," he added.

A CNN/WMUR poll of New Hampshire Republicans released Thursday evening showed Trump with 26 percent, Carly Fiorina with 16 percent and Rubio with 9 percent, marking an increase of just 2 points from the last poll for Trump but a 15-point jump for Fiorina and a 9-point increase for Rubio.

"Oh, wow. I mean these numbers are just astronomical for Marco Rubio," Cohen deadpanned. "If there's a debate tomorrow, Donald Trump is still front and center."

"I'd rather be in Donald Trump's position than in Carly Fiorina's position. I'd rather be in Donald Trump's position than in Marco Rubio's position. You don't have to win by 40 percent in order to win this race. You need to win by 1 percent. The guy is literally 18 points higher than anybody else," he added.

Trump has declined to go into specifics on how he would execute his plan to deport the 11 million people in the United States illegally, including during his Thursday telephone interview with Camerota.

"I think he will give specifics when he's ready to give the specifics," Cohen said. "Donald Trump will do what he says, and he'll do it under his timeline. Not yours, and not under the media's."

Addressing Trump's upcoming meeting with Fox News chief Roger Ailes, Cohen said that Trump just "wants to be treated fairly."

"What they're doing is they're marginalizing him, they're criticizing him, they're trying to figure out how to get this man out of the race," Cohen said of the network's coverage. "I do believe that they do not report Donald Trump fairly and they do not report him accurately."
