President Trump lashed out against Nevada on Twitter in the early hours of Monday, following the state’s legislature passed a bill for universal mail-in voting. Trump has frequently claimed, without evidence or the support of experts, that expansive mail-in voting will lead to fraudulent results and disproportionately favor Democrats.

“In an illegal late night coup, Nevada's clubhouse Governor made it impossible for Republicans to win the state,” Trump tweeted. “Post office could never handle the Traffic of Mail-In Votes without preparation. Using Covid to steal the state. See you in Court!”

The bill is currently awaiting approval from Nevada Gov. Steve Sisolak, a Democrat. Should it be signed into law, it would make Nevada the seventh state to send ballots to all registered voters. It already distributed ballots to its voters for during primaries and included and encouragement to avoid in-person polling stations.

California and Vermont have previously passed similar measures in response to the pandemic, while Colorado, Hawaii, Oregon, Utah, and Washington conducted their elections this way already.

Neither the Trump campaign nor Sisolak’s office has issued any statements on Trump’s incendiary Twitter remarks.

Despite Trump’s many claims, election security experts have stated that voter fraud is too rare an occurrence to warrant action. The practice is said to be even less common with mail-in voting.

Due to the public health issues, Trump has also raised the possibility of delaying the general election, a move many have criticized and compared to totalitarian tactics. Presidents do not have the authority to move the date of an election.
