BOCA RATON, Fla. (October 22, 2012)--As President Barack Obama and Republican rival Mitt Romney prepared for their final debate Monday tonight in Florida, some Romney allies were accusing the White House of leaking national security information for political gain.

They were talking about a new report claiming that the U.S. and Iran have agreed to hold direct negotiations.

Republican Sen. Lindsey Graham of South Carolina told Fox News that the timing is "pretty obvious."

Democrats responded that it's the Republicans who are playing politics with foreign policy.

With 15 days to go, the race appears to be tied.

Both candidates were taking 47 percent among likely voters in a Wall Street Journal/NBC News poll released Sunday.
