Responding to a tweet about MSNBC's ratings, which haven't been so hot in primetime as of late, Keith Olbermann took a shot at his former employer.
"It's about the collapse of that network," he said in a tweet Wednesday.
Olbermann also suggested that he isn't on speaking terms with MSNBC host Rachel Maddow. "I don't know anything about her any more," he said. "She hasn't bothered to speak to me since I left."
Olbermann and MSNBC famously parted ways in 2011 on bad terms, to say the least.
