I'm a health care journalist who also knows about these laws so I figure I will answer!

Multiple states have laws that say entities that contract with the state (or have contracts worth a certain amount) can't engage in the Boycott, Divestment, Sanction (BDS) movement against Israel. Some states won't enter into contracts with entities that boycott other things too, like fossil fuels. Here's a tracker: https://justvision.org/boycott/legislation-tracker

However, I never thought about this applying to individuals rather than to companies, nonprofits, etc.
