Why did the mainstream media accuse Andrew Brietbart of hacking a congressman's twitter?

[Alberto Del rios]

The breaking Anthony Wiener story took a new twist as the embattled congressman broke down into tears admitting he lied about sending the pics and also lied about being hacked. Why is the media so disinterested in this scandal? Why do they attack the messenger? How can the media have any credibility left in today's world?
@ Derail I understand that the American media is overwhelmingly liberal but hacking into a congressman's twitter account is a serious crime and should be investigated.

NBC didn't cover it at all with the statement, "There are more compelling issues to cover." Those "compelling" issues were anything that could be twisted into a negative about Sara Palin.

The point is, 3 days ago Weiner was verbally attacking anyone who asked him about the accusations. Now he admits his ill-doings. The media is primarily Leftist in their over all attitudes and give a pass to Democrats. They have entirely different standards for the the country's majority - the Conservative base.
