The United States Postal Service worker who claimed a postmaster in Erie, Pa., told employees to backdate ballots that were mailed after Election Day has admitted he made up the allegations, sources tell the Washington Post. The claim, which has been cited by top Republicans including Lindsey Graham as evidence of widespread voter fraud, was investigated by the USPS Office of Inspector General, and the sources say the worker admitted it was false and signed an affidavit recanting. But the worker himself is on YouTube refuting the Post story, and he tells controversial group Project Veritas, which Fox News describes as a "far-right activist group," that he was "coerced." The USPS investigation continues. (More US Postal Service stories.)
