No details about what particular behaviors sent Matt Lauer‘s career crashing into the rocks, but former MSNBC anchor Keith Oldermann tweeted this morning that NBC knew about Lauer’s sexual misconduct prior to getting whacked yesterday and that the network had chosen to “enable” and “bury” the issue rather than take action.

“Matt Lauer was [remorselessly] vindictive and tyrannical to everyone at NBC News and management repeatedly enabled him and buried the issue,” said Olbermann tweeted.

At the same time Prairie Home Companion creator-headliner Garrison Keillor, 75, has been cut loose by Minnesota Public Radio, but the term in this instance was “improper conduct,” or allegations of his inappropriate behavior with an individual who worked with him,” according to a statement from the radio network. The AP reported that he’d been canned over “a story that I think is more interesting and more complicated than the version M.P.R. heard.”
