Multiple people whose death sentences were commuted by former President Joe Biden could face new charges at the state level following pressure from President Donald Trump, according to The New York Times.

Last year, Biden commuted the death sentences of 37 people, a decision that Trump has repeatedly attacked.

Because Trump is unable to fully overturn the commutations, he’s instead urged regional prosecutors to pursue new charges, which could lead to death sentences at the state level, The Times notes.

In many places, authorities are unable to do this due to the time that’s passed in the case or state restrictions on capital punishment.

In at least four cases, however, state authorities have already pursued new charges, or could try to in the future. People can be prosecuted for the same crime at the federal and state levels, according to The Times.

Any such effort is expected to face a legal challenge, however, experts say.

These moves further highlight Trump’s ire about the commutations and his support for the death penalty.

Earlier this year, Attorney General Pam Bondi also moved several of the people who received commutations to a supermax facility in Colorado at Trump’s direction.
