(Newser) – The Keith Olbermann chronicles continue: The Daily Beast got hold of an internal email from a Current TV staffer relaying a little temper tantrum Olbermann reportedly had on set. It's not all that dramatic—he got angry over tech problems and threw a mug that shattered against a wall, according to the email—but it's another sign that "both sides seem intent on painting an unflattering picture of the other," writes Howard Kurtz. (Olbermann went on Letterman earlier this week.)

In fact, the staffer who wrote the email seemed to be really stretching to paint Olbermann in a bad light: "In addition, the spill left from the fluid (I assume water) could have caused someone to slip, which is also a dangerous condition," it reads. Olbermann's camp calls the email a "gross overstatement" of the incident. In another development, Olbermann did, in fact, file suit today against Current for wrongful termination, reports TMZ.
