Politico reports that Graham sent a letter to President Barack Obama on Tuesday. In it, Graham said he believes the audits were part of the IRS's admitted practice of targeting conservative and pro-Israel groups that came to light on Friday.

Graham says the organization, headquartered in North Carolina, ran statewide ads supporting a traditional marriage amendment in the state. 

In the fall, the ministry ran newspaper ads asking voters to "cast our ballots for candidates who base their decisions on biblical principles and support the nation of Israel." The ad concluded, "Vote for biblical values this November 6, and pray with me (Billy Graham) that America will remain one nation under God."
