(CNN) -- Kay Hagan erupted in anger Thursday over a television ad from Sen. Elizabeth Dole suggesting Hagan is "godless."

"I think Elizabeth Dole has just gone to the lowest of the lows," Hagan said of the ad during an appearance on a talk show on WPTF-AM in Raleigh, North Carolina. "This is an attack on my Christian faith."

Hagan, who described herself as a Sunday school teacher and an elder at a Presbyterian church in Greensboro, North Carolina, urged Dole to "pull this kind of despicable ad."

Hagan, who is challenging Dole's re-election bid, filed an application in a Wake County, North Carolina, court Thursday, seeking permission to file a complaint within 20 days, after the election is over.

"The advertisement purposely misstates facts about the plaintiff," said the three-page application, which was filed in District Superior Court.

In the 30-second ad, a narrator says that a leader of the Godless Americans Political Action Committee recently held a "secret fundraiser" for Hagan.

The ad then shows members of the group, which promotes rights for atheists and the separation of church and state, declaring that neither God nor Jesus exists.

"Godless Americans and Kay Hagan," the ad continues. "She hid from cameras. Took 'Godless' money. What did Kay Hagan promise in return?"

The ad ends with a picture of Hagan and a voice that sounds like hers declaring, "There is no God."

But the application said Hagan never made that statement or accepted money from the group.


The GOP can kiss that seat goodbye
