CHICO Calif. - A heated battle between Audrey Denney and incumbent Congressman Doug LaMalfa is getting muddy.

Audrey Denney claims Doug LaMalfa's campaign doctored a picture of her and sent it out to everyone in the district.

Audrey Denney claims Doug LaMalfa's campaign took this picture of her pledging not to take money from big oil and changed to a photo of her signing a pledge to Congresswoman Nancy Pelosi.

"A photo from my facebook feed had been photoshopped to make false accusations about me and so we posted the photoshopped version and the original version on our social media feeds to let the residents of the first district know what was truth and what was not truth," Denney said.

The original picture is more than six months old.

"So the picture that was photoshopped was a picture of me signing a pledge from February this year to not accept any corporate contributions from big oil and other industries and that the text of the pledge that I had signed had been erased and they had inserted other text," Denney said.

Action News Now spoke with Dave Gilliard, Congressman LaMalfa's campaign spokesman, on the phone and he said they stand behind the doctored image.

"That photograph was taken from a campaign website it's obviously a parody and she needs to go back and look in the mirror, Audrey Denney has got her hands dirty all over this, she's got a lot of explaining to do," Gilliard said.

Denney said this isn't going to distract her from running her campaign.

"I've gotten emails calls and texts from people all across the political spectrum that like me see it as a laughable old trick to get people to believe falsehoods," Denney said. "We're not gonna let this distract us from what we're doing."
