Kirsten Powers slammed President Obama for once again taking a shot at Fox News, saying the president has had an "obsession" with going after Fox since he took office. 

Obama referenced Fox News in criticizing how the media has covered issues related to poverty. 

"I think the effort to suggest that the poor are sponges, leeches, don’t want to work, are lazy, are undeserving got traction," Obama said. "And look, it’s still being propagated. I have to say that if you watch Fox News on a regular basis, it is a constant menu. They will find folks who make me mad. I don’t know where they find them."

In her new book, The Silencing: How the Left Is Killing Free Speech, Powers explains in detail how the left frequently accuses critics of being racist or sexist instead of having a real debate about the issues. 

She argued that the administration's systematic attempts to "de-legitimize" Fox News are a part of that overall strategy to shut down the other side. Powers recalled that the administration has cut Fox News out of interviews and then lied about doing it. 

Powers wondered what the reaction would have been if George W. Bush had taken this sort of stance toward MSNBC.

"They just want to silence people who are disagreeing with them. They haven't been successful with Fox, but that doesn't make what they did any less nefarious or any less wrong. ... What the president said - basically blaming Fox News for the debate on poverty - it's absurd, it's gratuitous, it's beneath the office of the president," she said. 

Watch the discussion above, as Powers and Martha MacCallum also discuss a Democratic senator's accusation that President Obama displayed sexism toward Elizabeth Warren.

Powers noted that the accusation from Sen. Sherrod Brown is yet another example of what she's talking about.
