New York City businessman and billionaire Donald Trump said Tuesday that he has been contacted by a group looking to purchase the Buffalo Bills.

"People have actually talked to me about the Bills," Trump told WBEN radio in Buffalo, N.Y. "I mean, the group of people called me -- would I be interested in investing, and I'll take a look at it. I mean, I look at a lot of things. I'll take a look at it."

Since the death of owner Ralph Wilson last week, speculation around the Bills' future in Buffalo has increased. Trump said he would like to see the team stay in the city.

"I know so many people in Buffalo, and they have asked me about looking at that and I certainly would look at it, but I would ... if it were me, I'd keep the team in Buffalo," he said. "I think it's something that is really vital to the area. ... It would be catastrophic, in my opinion, if Buffalo lost the Buffalo Bills."

Trump said he is "very good friends" with former Bills quarterback Jim Kelly, who is undergoing treatment for cancer in New York City.

"He called me, and actually his family is staying at one of my apartments in New York as he's going through a very rough time," Trump said. "He's a great guy, and he sounded actually really good two days ago. He called me from the hospital."

Kelly said in a 2010 interview with ESPN that he would try to keep the Bills from relocating after Wilson died.

"I do have people in line that will want to purchase the team and keep it in western New York because I do not entertain any offers from anybody looking to move the Buffalo Bills from western New York," Kelly said. "I just won't do it. I'll do whatever it takes to keep them in Buffalo."
