Reacting to Melissa Harris-Perry‘s apology to the Romney family for a segment on her MSNBC show last weekend, ESPN2′s Keith Olbermann swiped at his former employer.

“Any adults in charge over there [at MSNBC]?” Olbermann, a former MSNBC host, tweeted Tuesday.

As part of a “game” on her last show, Harris-Perry and a panel of guests mocked a photo of Mitt Romney and his family, including his adopted black grandson. Harris Perry and two other panelists apologized separately after the segment aired.

One of Olbermann’s followers replied to Olbermann’s dig at MSNBC. “You’d have been laughing along with them,” he tweeted at the former political commentator.

“Bullsh*t,” Olbermann said in return.

It’s not the first time Olbermann has taken aim at his old stomping grounds. “It’s about the collapse of the network,” he tweeted last July, regarding a a series of poor ratings reports at MSNBC.
