Years of tension: Inside MSNBC’s rocky marriage to Olbermann

Inside the offices of MSNBC, staff members grew more restive about Mr. Olbermann’s temperament. Some days Mr. Olbermann threatened not to come to work at all and a substitute anchor had to be notified to be on standby…

At the same time, stories about Mr. Olbermann’s thin skin circulated widely in the newsroom. One such story, which was recalled independently by two hosts, dates to early December, when Mr. O’Donnell, then carving out some success as the 10 p.m. host on MSNBC, collegially proposed via e-mail that Mr. Olbermann come on his show to talk about President Obama’s tax-cut compromise.

Mr. O’Donnell had written this post on Twitter: “Liberal critics of the Obama deal say exactly what Pat Buchanan said of George H. W. Bush: he’s weak.” The message speculated that Mr. Obama’s critics would do to him what Mr. Buchanan “did to H.W. Bush: destroy him and help elect a president from the other party.”

Mr. Olbermann apparently interpreted the message as a personal attack; he declined to appear on Mr. O’Donnell’s show. “I saw what you wrote on Twitter,” he snapped at Mr. O’Donnell.
