One of the laws of physics is that you cannot measure a particles position and its momentum.
But what if the particle to be measured is quantum entangled with another particle?

As previously noted, see the EPR paradox. Bell’s theorem also discusses this idea.

wait but what if you measure its energy, at a given time
wait

Here’s a way to think about it:
For two particles to be entangled, they must interact physically, so they must be together. They must them move apart, and be sufficiently far removed from each other that when one is measured it can’t communicate (at or below light speed — the fastest speed information can travel) with the other. Measuring the properties of interest involved having the particles interact with the measuring equipment, and the measurements must be simultaneous.
The only way to have the measuring equipment in the right place to measure the momentum of one and the position of the other is to know in advance where they are going to be at that time, which can only be determined if the experimenter knows the momentum and velocity of the particles immediately after they interact. That is, you need to know the properties you’re trying to measure before you try to measure them.
There’s also the slight issue that SR disclaims simultaneity.

so the experimenter is a politician
