Was wondering the same thing...heard him on the CBS hourly the day Scott McClellan resigned as WH press secretary. He was on the phone offering some comments...and ID's a CBS correspondent, and here appears to be the answer, from a story about McClellan's going away party/last briefing today at the WH:McClellan and his wife Jill were toasted and hailed with jokes and poetry. Recorded messages from CBS White House Correspondent Mark Knoller (who is in Sibley Hospital recovering from an ailment) ........Guess Mark has been sick...hope he returns soon...
