Trump alleges 'shocking vulnerabilities' in US election security ahead of midterms

Elsewhere in the speech, the president alleged that US voting machines are "extremely exposed" to interference by foreign adversaries, including Russia, China and Iran.Shortcomings of US election infrastructure have been well-documented. Some were addressed after the 2016 election which Trump won, after the US intelligence community found that Russia had engaged in a concerted election meddling campaign that included hacking, social media influencing and funding of on-the-ground electioneering activities.During the address, Trump also alleged that a state investigation by Michigan law enforcement discovered a voter registration fraud scheme by a Democratic-affiliated group, but was constrained by the FBI from taking action before the statute of limitations expired."It was pay, play and cheat," he said, although he provided no evidence of votes or tabulations being changed or voting machines hacked.Separately, Trump said that the Department of Homeland Security had identified 278,000 non-citizens were registered to vote. He did not say whether any of those people had voted or had an impact on any election outcome.At the end of his speech, Trump again called for the passing the of the SAVE America Act, which bans most mail voting, requires proof of citizenship for voter registration and photo ID to cast a ballot.That legislation has been stalled in the Senate for months.
