BEIJING, Oct. 25 (Xinhuanet) -- A Republican campaign worker has admitted she made up the story that she was attacked by an "African-American man" angered by a John McCain sticker on her car, according to media reports Saturday.

    The worker Ashley Todd, 20, of College Park, Texas, will be charged with making false report to police and may face more charges, said Maurita Bryant, the Pittsburgh, Pennsylvania, assistant police chief at a briefing Friday.

    "This has wasted so much time. It's just a lot of wasted man hours," Bryant added.

    Todd's report to the police said a man approached her Wednesday night at an ATM in Pittsburgh's East End, put a blade to her neck and demanded money. 

    Her statement: a man "punched her in the back of the head, knocking her to the ground, and he continued to punch and kick her while threatening to teach her a lesson for being a McCain supporter." 

    But after police investigation, "several inconsistencies" were found in her report as firstly she did not appear in surveillance videos taken at the ATM. Then she was also asked to take a polygraph test, with the results still up-held by the police.

    A last, she came up to the police station and "wanted to tell the truth" -- that she was not robbed, nor was there any attacker, any "African-American."

    When asked whether the false report was politically motivated at the same briefing, Bryant replied, "It's difficult to say."

    "She is stating that she was in her vehicle driving around, and she came up with this idea," Bryant added, noting there was no indication that anyone else was involved.

    However, before the police revelation of the falsehood, McCain spokeswoman Jill Hazelbaker said that McCain and running mate Alaska Gov. Sarah Palin "spoke to the victim and her family after learning about the incident."

    On its part, the Obama campaign said it also had issued a statement wishing "the woman speedy recovery."
