I don't. However you might try asking one of these 14 Dems, since they were all in the US Senate at the time and must have approved the choice as well...
Heflin, Shelby -AL, Bumpers, Pryor -AR, Graham -FL, Nunn -GA, Johnston, Breaux -LA, Ford -KY, Sasser, Mathews -TN Hollings -SC, Robb -VA, Byrd -WV
Uh-huh. Yeah. Must have been one of them. Not somebody like Teddy Kennedy, Bob Kerrey, or Paul Sarbanes.
