Donald Trump has called for November’s presidential election to be postponed, saying increased postal voting could lead to fraud and inaccurate results.
He suggested a delay until people can “properly, securely and safely” vote.
There is little evidence to support Mr Trump’s claims but he has long railed against mail-in voting which he has said would be susceptible to fraud
US states want to make postal voting easier due to public health concerns over the coronavirus pandemic.
In a tweet, Mr Trump said “universal mail-in voting” would make November’s vote the “most inaccurate and fraudulent election in history” and a “great embarrassment to the USA”.
Earlier this month, six US states were planning to hold “all-mail” ballot elections this November: California, Utah, Hawaii, Colorado, Oregon and Washington.
These states will automatically send postal ballots to all registered voters, which then have to be sent back or dropped off on election day – although some in-person voting is still available in certain limited circumstances.
