WASHINGTON - U.S. officials said Wednesday there has been no intelligence to suggest that foreign countries are working to undermine mail-in voting and no signs of any coordinated effort to commit widespread fraud through the vote-by-mail process, despite numerous claims made by President Donald Trump in recent months.The officials at multiple federal agencies stopped short of directly contradicting Trump, but their comments made it clear they had not seen evidence to support the president's statements that voter fraud will be rampant in the upcoming election and that the expected surge in mail-in ballots due to the coronavirus pandemic leaves November’s presidential election especially vulnerable to foreign interference.RELATED: Top US.
