Graham says his favorite app is Fox News

When the GOP presidential candidates at Wednesday night's "undercard" debate were asked about their favorite smart phone apps, Sen. Lindsey Graham was quick to respond with "Fox News."

“We’re at a Republican primary here,” said the South Carolina lawmaker.

Louisiana Gov. Bobby Jindal said he doesn’t have an iPhone and that he plays a game on his Blackberry and uses it to check the news online.

Graham and Jindal were joined by former Pennsylvania Sen. Rick Santorum and former New York Gov. George Pataki at the debate in Boulder. Colo. All four are polling no higher than 10 percent.

Santorum said he has an app for the NFL and The Wall Street Journal.

Pataki says he has one for the driver service Uber, which he uses frequently.

Grahams also quipped that that only reason he has an iPhone is because he gave his number to fellow GOP contender Donald Trump, who in a spat gave out Graham’s number.

“Don’t do that,” Graham said Wednesday night.

In response to Trump’s giving out his number, Graham destroyed the flip-phone in a video.
