Though Carters pardon was not specific to Clinton. From The MacNeil/Lehrer Report -- January 21, 1977 CARTER'S PARDON:

Just a day after Jimmy Carter's inaguration, he followed through on a contentious campaign promise, granting a presidential pardon to those who had avoided the draft during the Vietnam war by either not registering or traveling abroad.

The pardon meant the government was giving up forever the right to prosecute what the administration said were hundreds of thousands of draft-dodgers.
