What does this say about NBC/MSNBC?

Representative Charlie Wrangel had a very telling exchange with Luke Russert of MSNBC over the Representative’s ethics problems http://www.politicsdaily.com/2010/07/23/charlie-rangel-luke-russert-spar-over-dumb-question-in-ethics/
Luke Russert asked Mr. Wrangel if he feared losing his job to which the Representative asked “What station are you from?” to which Russert responded “NBC, MSNBC.” After asking more questions, Russert was told “It doesn’t really sound like NBC asking these dumb questions.” He continued that “It just shows what is really happened (sic) to a channel that did have some respect.”
Does Rangel’s comment that it doesn’t really sound like NBC asking these questions reflect the fact that heretofore the channel hasn’t been asking hard questions of him and some of his colleagues…..that it’s been derelict in its journalistic responsibility to the public?
