Republican Debate 2012: Santorum Says Paul 'Caught Not Telling the Truth'

At Saturday night's GOP debate in New Hampshire for the 2012 primary set on Tuesday, Rick Santorum accused Ron Paul in the early going of not telling the truth.

In the early minutes of the debate, held at Saint Anselm College in Manchester, New Hampshire and sponsored by ABC News, Yahoo! News, and WMUR News, it was Ron Paul's turn to talk early in the debate. He was asked if he stood by an ad suggesting Santorum was the most corrupt in the race.

When he first spoke, the microphone hummed with feedback due to a sound system issue.

Upon the mic hum when Paul spoke, Santorum quipped that Paul was caught not telling the truth.

Paul made a surprised face back at the accusation, but didn't verbally respond.

Approximately one in three New Hampshire voters remain undecided ahead of Tuesday's Republican presidential primary. As a result, the New Hampshire 2012 Republican debate tonight could play a big role in deciding the state's winner if one candidate gets an edge. Former Massachusetts governor Mitt Romney is the front-runner in New Hampshire according to most polls at the moment, but the final outcome of the first 2012 primary remains up for grabs.

Participants in the New Hampshire primary GOP debate included former House Speaker Newt Gingrich, former Utah Governor Jon Huntsman, Rep. Ron Paul (Texas), Gov. Rick Perry (Texas), former Massachusetts Governor Mitt Romney and former Pennsylvania Senator Rick Santorum

Moderators for the event are ABC anchors Diane Sawyer and George Stephanopoulos, joined by WMUR-TV anchor Josh McElveen.
