Whether or not he could is largely irrelevant. Executive orders can be completely undone by the next administration. Plus I’d wager this is out of scope for an executive order. Executive orders generally have to do with operations issues with the federal government.

He can issue an executive order to limit the number of immigrants can cross the US-Mexico border per day because that’s an operational issue for an agency within the executive branch. He can’t say, “Everyone can have access to IVF”. Essentially, he’d be saying that individual states can’t make illegal, IVF procedures. That’s a legislative policy issue, and would be up to congress to pass a law that would force the states to fall in line.

That’s my understanding at least. I’m sure I’ve mucked something up in that explanation, but would wager that the overall gist of it is correct.

https://en.wikipedia.org/wiki/Executive_order

Presidents don't make laws, congress does. There would have to be something in the constitution or in a law already passed that gives the executive branch the power to do that. An executive order is just an enforcement, a more specific guidance of application of already existing laws or powers. If the law the article is talking about is passed, he could issue executive orders to delineate more specific actions to help make sure it is enforced.

If Biden just sat down in a chair one day and wrote "I declare state laws and state constitutions restricting ivf are void!" like some kind of dictator it would do literally nothing.

Go on to the federal register and look at some executive orders. You'll find most of them pertain to things the president directly controls, like the operations of executive department agencies. When it's not something the president clearly controls in the constitution, it will cite the authority of which specific laws it's basing this on.

Purpose.

The National Space Council (Council), as authorized under Title V of Public Law 100-685, advises and assists the President regarding national space policy and strategy. This order sets forth the Council's membership, duties, and responsibilities.

So for an example, here's what law passed by congress this executive order is fulfilling, here are my more specific instructions about how we as the executive branch are going to fulfill that law. Clearly the authority to establish a national space council does not come from the constitution, so it's a law passed by congress that makes this order possible.

If congress passes a law protecting ivf and gives some power to the executive branch to enforce those protections, then maybe there would be situations where an executive order would be helpful.

And Biden clearly supports this law, has repeatedly urged congress to pass it, and headlined the issue in his state of the union address.

Looks like someone wasn't taught about separation of powers...

Executive orders only control the executive branch/manage the federal government, and certain other things the president has control over (like elaborating on an already-in-place law), they can't make or pass laws. Executive orders that overreach can be found invalid and blocked. The president can't just use laws as a suggestion.
