Of course some idiots claim the 10th amendment prohibits him from forcing states to so.
That is totally not true.

States do have power to do their own thing so long as it doesn't violate the US Constitution.
States do not have the right to violate the rights given to them by the US constitution.

And of course these lockdowns and restrictions violate the 1st and 14th amendments. Contact tracers violate the 4 the and 5th amendment.

So Trump does have the right to open up force states that are refusing to open up.

Of course he doesn't do it because he's part of the New World Order, just like Obama was along with both democrats and Republicans.

Here's the 10th amendment


[b[The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

So see states are permittee to do what they want so as long as they follow the US constitution but they are not allowed to violate the US constitution.
And if they do then the president has the right to step in and force the states to follow the constitution and repeal any laws that violate the US constitution.
