Unfortunately that just isn't something you can really sue for.

You can sue the administration putting the rules in place, but you can't sue someone for saying something that's then picked up by another person, and another, and so on until the president happens to hear about it.

It's why, for example, financial sites will always have the disclaimer "this is not financial advice, seek the advice of a licensed financial professional, etc, etc", because financial harms are often covered, (while other things affected by lies are not in most circumstances) when that lie is something you took action on, and that action caused you harm (e.g. "this stock is going to double tomorrow", you buy it, it crashes)

But you can't sue when that lie caused someone else to do something that indirectly caused you harm. (e.g. "this stock will crash in a week", billionaire sells a ton of the stock, your retirement portfolio drops in value) In that case, only the billionaire would be eligible to sue the person who lied to them.

You might be able to sue Nick Shirley if you ran a daycare business and his false claims about your daycare caused your daycare to get attacked, but you couldn't sue him if he lied about a daycare down the road and mobs started attacking every daycare in town because they just assumed all of them were at fault, and you certainly couldn't sue if the claims he made then got to the social media feeds of some locals, which then caused local food banks run by those locals to stop offering food because they thought there's a chance it could be obtained by scammers instead of those in need.
