As did Carter for the Vietnam Draft Dodgers, but I have question as to whether an “amnesty” of a group, a decision to nol pros, is in fact a pardon.
A parson cannot be reversed, but amnesty may be reversible.
Back to my law books tonight.
Amnesty is frequently used to describe legislation and executive orders (to suspend prosecution) that can be reversed. However, there is also an official Presidential pardon applied to a group that is also known as amnesty.
I’m not sure if the terminology changes a bit and the term ‘clemency’ is used, but it certain that there is amnesty (by whatever name) that carries the full status of pardon as in the Ex Parte Garland ruling.
