GRETA VAN SUSTEREN, FOX NEWS HOST: Right now, Sergeant Tahmooressi is not there, but his case is being presented to a Mexican judge. The Marine has already spent more than five months in prison.

And Donald Trump wants to know why President Obama hasn't asked Mexico's president to fast-track the case.

Donald Trump joins us. Good evening, sir.

DONALD TRUMP, PRESIDENT & CEO, TRUMP GROUP (Via Phone): Hi, Greta.

VAN SUSTEREN: What are your thoughts about this case?

TRUMP: It's not even believable. It's not believable that our president wouldn't call, and if he did call, he'd be out in 10 minutes. At least, they have to have some respect for him. They obviously don't have much. But it's inconceivable that our president wouldn't put in one call or one meeting to get him out, just inconceivable.

VAN SUSTEREN: What would you do if you were president?

TRUMP: I would not even waste my time with a meeting. I would make a call. And if that young man, Andrew, was not released within 10 minutes of that call, there would be hell to pay in Mexico. And I mean, economic hell. We support them. We give them tremendous amounts of subsidy and business and commerce, and so many other things that, frankly, we shouldn't be giving them.

And for them to disrespect us to that extent, where a Marine, who made a mistake, or whatever -- I mean, you look at our borders, Mexicans are flowing across our borders like it's water, and yet, the only one who can't come across the border is Sergeant Tahmooressi. So I would make one phone call, and I guarantee you, he'd be out very, very quickly. And Obama could do the same, if he were competent.

VAN SUSTEREN: Donald, you're not the only one who's upset. I get emails every single day from Marines, from family members who have served, Americans who have never served, but they're grateful to Sergeant Tahmooressi who did two terms in Afghanistan, got hit with an IED, suffers from PTSD, was trying to get help from a V.A. hospital -- and I don't even want to go into that discussion -- but people are very upset about this.

TRUMP: They're very upset. And I hear it all the time. Every time I even speak about it, whether it's your show or "FOX & Friends" or something else, because I'm very upset about it also. It's just an inconceivable situation that our government doesn't do something immediately to get him out. And not only that, it's a rough place. They're beating the hell out of him. I hear he's living in hell. I see his mother. I just see on your show, his mother going over there, and what she's going through is incredible.

When you see the borders, they're like a sieve. The people are pouring, Mexicans and anybody wants to come in. They are just pouring across our borders. And yet, he's stuck in a jail, a rough place. It's 110 degrees. And I think it's a disgrace. I think it's disgraceful that our president doesn't take care of him immediately. And it should have been done a long time ago. I mean, even now, it's so ridiculously late.

VAN SUSTEREN: Yes.

TRUMP: But the proper phone call, Greta -- and it doesn't have to be a meeting -- a phone call, he'd be out of there in five minutes.

VAN SUSTEREN: Donald, always nice to talk to you. Thank you, sir.

TRUMP: Thank you very much.
