Nevada Governor Steve Sisolak has signed into law a bill to expand universal mail-in voting across the state as the US continues to feel the impacts of the COVID-19 pandemic and attempts to navigate upcoming elections. The bill, passed along party lines, directs election officials to mail a ballot to every active registered voter in the state. The envelope will also include instructions, a return envelope, and a sleeve to ensure privacy.

Democratic Party leaders in Nevada have argued that the new law is needed to slow the spread of COVID-19. They also suggested that mail-in voting will prevent voters from waiting in long lines, an issue that had previously delayed primary election results in June.

President Donald Trump responded on Twitter, characterizing the bill signed Monday as an “illegal late night coup” and stating that the “Post Office could never handle the Traffic of Mail-in Votes without preparation.” Trump, who has publicly referred to the postal service as “a joke,” has also faced criticism from former President Barack Obama for allegedly attempting to suppress votes in the upcoming 2020 election. President Obama said at Congressman John Lewis’s funeral last Thursday that “There are those in power doing their darnedest to discourage people from voting… even undermining the Postal Service in the run-up to an election that is going to be dependent on mailed-in ballots so people don’t get sick.”

Trump has already indicated that his administration plans to file a lawsuit challenging the Nevada bill.
