On MSNBC’s The Last Word Tuesday night, Chris Hayes questioned why conservative blogger Andrew Breitbart was allowed to “spout off” on CNN about Rep. Anthony Weiner (D-NY). Breitbart implied Tuesday that Weiner had been engaged in inappropriate relationships with multiple young women.

“Am I wrong in my level of outrage that this person who has been so discredited, so many times, is such a serial manipulator of the media is allowed to just come on and spout off like this?” he asked.

“Andrew Breitbart is not known to be the most self-reflective, remorseful person,” his guest, Huffington Post’s Alex Wagner added. “I think in that same interview he talked about the Shirley Sherrod story being a liberal attack on him.”

As they also noted, Wagner didn't think Rep. Weiner did himself any favors by refusing to answer direct questions during his press conference today and I agree. That said, it was pretty astounding to see CNN going after him the way they did on the word of a known liar like Breitbart and allowing Breitbart on the air earlier today to attack him, where even their legal analyst, Jeffrey Toobin called out his own network for their behavior.

Following Breitbart’s interview, CNN legal analyst Jeffrey Toobin told host Randi Kaye that he regretted the network allowed Breitbart to make those claims.

“What Andrew Breitbart was insinuating about [Weiner] with young girls and stuff is outrageous,” Toobin said. “And frankly, it’s too bad that he got to say that stuff on CNN.”
