Trump can not interfere with state trials or verdicts, and can’t pardon people for those crimes.
The Alex Jones case was heard in Texas state court, and the falsifying business records crimes that Trump was found guilt of were state of New York crimes.
So he can’t pardon himself, and he can’t pardon Jones.
The President’s clemency power is conferred by Article II, Section 2, Clause 1 of the Constitution of the United States, which provides: “The President . . . shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.” Thus, the President’s authority to grant clemency is limited to federal offenses and offenses prosecuted by the United States Attorney for the District of Columbia in the name of the United States in the D.C. Superior Court. An offense that violates a state law is not an offense against the United States. A person who wishes to seek a pardon or a commutation of sentence for a state offense should contact the authorities of the state in which the conviction occurred. Such state authorities are typically the Governor or a state board of pardons and/or paroles, if the state government has created such a board.
And, given that his sentencing has been deferred until his term as President ends, when he is no longer president, Trump can still go to jail and that looming sentencing will be there with him in the bedroom at night when he tries to fall asleep.
So - for every person thinking that by being elected Trump has successfully avoided all of his legal problems, HA HA HA HA no.
Schadenfreude is a dish best served cold.
