On his Twitter account, Trump said that with universal Mail-In Voting, 2020 would be the most inaccurate & fraudulent election in history.

"It will be a great embarrassment to the USA. Delay the Election until people can properly, securely and safely vote?" he said.

Under the US constitution, the president does not have the authority to postpone the election himself. Only Congress can delay the date for the general election for president. (ILKHA)
