US Officials Confident in Election Security as Voters Head to Polls Jeff Seldin WASHINGTON - Officials overseeing U.S. election security are expressing confidence as voters across the country head to the polls to cast ballots for president and a multitude of state and local races. Millions of Americans were expected to vote in person Tuesday, the last day for citizens to cast a ballot, in addition to the more than 100 million, who voted by mail or at early voting centers. And despite indications that U.S. adversaries will try to disrupt the election process, early evidence suggests any such attempts have failed to make an impact. "We have no indications that a foreign adversary has succeeded in compromising or affecting the actual votes cast in this election," acting Homeland Security Secretary Chad Wolf said at a briefing just hours after the first polling sites opened their doors. "Our election infrastructure is resilient," he said. "But we do remain on high alert." U.S. officials have already acknowledged at least two attempts to penetrate systems seen as critical to elections in recent weeks, one by Iran and one by Russia. In both cases, hackers were able to steal information related to voter registration databases, with Iranian hackers managing to infiltrate one state's database and use that information as part of a disinformation campaign. .
