The Senate was dominated by the DemonRats back then...which senators put up McPherson's name to the panel? I'd be interested, if you happen to know.
Latschar, of course, was appointed by DIRTXPOTUS.
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
