Trump reads Lindsey Graham's phone number out at campaign rally (VIDEO)

LUFFTON, S.C. (AP) — If you're looking to get ahold of Lindsey Graham, now might be your chance.

During a crowd of more than 500 in Bluffton, South Carolina, on Tuesday, real estate mogul and GOP presidential contender Donald Trump read out his fellow presidential contender's cell phone number.

Trump says Graham gave him the number several years ago, saying the "total lightweight" had been seeking his help for a deal with Fox News Channel.

Trump said he agreed to do so and took down Graham's phone number, which he wrote down on a piece of paper, saved, and showed to the crowd on Tuesday.

Trump encouraged the audience to give the number a call. One man did and called out that it said the senator was not available.

Graham, for his part, appeared to take the action in stride.
