"The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment." - US Constitution
Pretty open ended and nearly absolute.
Who you elect to POTUS is important. If you allow a theft to stand that is important also.
Time to pardon those who had the courage to oppose the theft and got put in jail for it.
Unless you put your butt on the line on Jan 6 2020 and went to jail then IMO you just like me have no "right" to object to the former Thief in Chief pardoning anyone. The time for outrage was Jan 2020. These pardons are just the final chapter in the sorry saga that was the Joe Biden "presidency."
