The Office of the Pardon Attorney, part of the Justice Department, maintains the official record of every pardon, commutation, and other act of clemency a sitting president grants, updated as grants are issued.
It is deliberately bare: names, offenses, and the type of clemency granted, with none of the context — campaign donations, family connections, business relationships — that turns a bare grant into a "pardons for favors" story.
That bareness is exactly its value here. Before accepting any reporting about a pardon's motive, this is the place to confirm the grant itself actually happened, and when — the same role the DOJ's own numbers play in verifying any other "logged, not counted" entry on this site.
Cross-referencing this list against campaign-finance and clemency-petition records is how outlets like Forbes and the watchdogs cited elsewhere on this page build the pay-to-play case; the primary record is the necessary first step.
