Nashville (AP) -- Actor and Former US Senator Fred Thompson says his potential Republican opponents are trying to dig up dirt on him while he considers running for the White House.
Thompson said on Fox News Channel's "Hannity and Colmes" that he was surprised to hear opposition researchers were combing through public records in Tennessee.
Thompson says he thought the investigation might be coming from Democrats, but found it was by other Republicans.
Thompson compared the digging to "gnats swarming around a war horse," saying it's irritating, but not that important.
Perhaps best known for playing district attorney Arthur Branch on NBC's drama "Law & Order," Thompson has said he hasn't set a deadline to make a decision about running for President and that he could wait until summer.
