No shade to the linked commenter, as this is a common misconception.

Rule 2: the federal government and each state government are “separate sovereigns” so both have the right to try the same act as a crime. The “separate sovereigns doctrine”says this is not double jeopardy even if the crime being charged has all the same elements; the Supreme Court upheld this in 2019, with Ginsberg/Gorsuch as surprising co-dissenters.

In fact, you could theoretically be tried for the same act by all 50 states and the federal government. The idea is that a crime is committed against the public, so each affected government has the right to seek recourse.
