J Stanley Pottinger, US official who discovered identity of Watergate scandal's 'Deep Throat', passes away
He was with Richardson on the evening of Oct. 20, 1973, when Nixon ordered Richardson to fire Archibald Cox, the special counsel investigating the Watergate break-in. When Richardson refused, Nixon fired him; when William Ruckelshaus, the deputy attorney general, refused in turn, Nixon fired him as well.
