WASHINGTON (NewsNation Now) — The federal agency that oversees U.S. election security is pushing back at unsubstantiated claims of voter fraud.

A new statement from the Cybersecurity and Infrastructure Security Agency notes that local election offices have detection measures that “make it highly difficult to commit fraud through counterfeit ballots.”

CISA, a component of the Department of Homeland Security, published the statement Friday on a section of its website devoted to dispelling rumors. It said it was countering a rumor about the role of DHS and CISA in the printing of ballots and auditing of results. Neither agency has a role in printing or auditing ballots. CISA principally helps local and state election departments protect themselves against cyberattacks.

CISA also put out a statement noting that the systems and processes used to tabulate votes and certify results “are protected by various safeguards that help ensure the accuracy of election results.”

The agency has been urging the public for weeks to be patient during the counting of results, which was slower this year in large part because of COVID-19 and the large number of mail-in ballots. It has made no comment on Trump saying without evidence that the ballot-counting process is unfair and corrupt.
