I'm just putting this out there for what it's worth. This is an un-vetted, unverified, uncorroborated rumor from social media.
Some people in political circles are stating that the Legislature is being called into a special session over the COVD-19. This information supposedly comes from legislators directly. A state income tax, details unknown, is planned to be announced.
The state constitution requires two votes, in separate sessions, so a 2020 special session would be the first vote and the second vote would be in the 2021 regular session. Following that, the income tax must be approved on the ballot by the voters before it becomes law.
As for any details about guns, that's unknown. Special sessions can only deal with the reason they are called, the COVID-19 crisis, and it would be difficult to work a gun control bill in, but not impossible.
A week ago, the Nevada Appeal speculated that despite the fiscal emergency declaration Sisolak was not calling a special session.
We will let you know if we receive additional information.
