MSNBC is so liberal that even the left-wing Stephen Colbert wouldn’t buy the idea that the network is objective. Network host and Chief Legal Correspondent Ari Melber appeared on The Late Show Tuesday night. Not surprisingly, the Mueller probe came up.

After Melber and host Stephen Colbert analyzed and discussed the prospects for impeachment, the MSNBC host insisted, “We’re not reporting it out gunning for one outcome.”Colbert shockingly pushed back on Melber’s claim of objectivity: “Come on…you guys bang a drum over there sometimes.”

The discussion focused primarily on the standoff between the executive branch and the House of Representatives, with Colbert asking Melber: “What the hell is going on right now?” and “Are there still laws Ari Melber?” To the delight of Colbert and his liberal audience, Melber declared that “Bob Mueller found evidence that Donald Trump committed five felonies in office.” Channeling his inner Jerry Nadler, Colbert asked “isn’t that the definition of a constitutional crisis? You get to a point where the Constitution did not deal with this level of obstruction...and the system breaks down.”

Colbert also complained that Trump administration officials “flout the constitutional norms in broad daylight and nothing seems to happen.” Eventually, Colbert asked Melber what “The people over at the People’s Republic of MSNBC” think of impeachment. Melber responded: "I think there is substantial evidence in the Mueller report that the President committed crimes in office.”

Melber seemed to believe that the Democrats have not been strong enough in their push for impeachment: “now they’re saying, ‘well, we don’t want to impeach because of politics.’ I don't think that’s a good reason to do anything, really.” When Melber proclaimed that “we’re not reporting it out gunning for one outcome,” Colbert shockingly pushed back: “you guys don’t advocate at all over at MSNBC? You guys, come on...you guys bang a drum over there sometimes.”

Melber once again tried to pass himself off as objective before the interview came to a close: “On The Beat, we’re not advocating for an outcome.”

The facts tell a different story. Just weeks ago, the MSNBC host expressed his hope that the “hidden Mueller report” would contain “very substantial” information damaging to President Trump. In an awkward attempt to compare Attorney General Bill Barr’s four-page summary of the Mueller report to a 1996 love song entitled “Four-Page Letter,” Melber made many of the same points that he made on The Late Show.

Melber declared that the Democrats were “still trying to be careful, thinking about whether they put too much love or faith in the Mueller investigation” after arguing that “a four-page letter isn’t going to cut it for Congress to make an informed judgment about what the President did.”

Weeks later, Melber ended up complaining about the Democrats’ reaction to the Mueller report on The Late Show: “I think it is fascinating and kind of silly that the Democrats in Congress have talked for so long about wanting to get Mueller’s report” and when they finally got it, they hesitated to take decisive action on impeachment.

When even Stephen Colbert scoffs at the idea of your objectivity, it might make sense for Melber and the media to step back and examine the crisis of confidence they have created by their biased reporting.
