The bill would remove first cousins from the list of family members with whom it’s illegal to have sexual relations in the state.
Edit: there is an update to this story and Rep. Nick Wilson has withdrawn the bill saying it was filed in error. See the new thread.
Not too sure about the existing laws, but it looks like it was going to be illegal in the first draft but someone officially crossed out “first cousin” in the final draft of this legislation.
This is just how bills are filed when they’re intended to amend a law. The law as it’s written is included, and parts are struck out, added, etc. It’s basically track changes.
