NEW YORK (AP) — Keith Olbermann says he is so certain President Donald Trump will be impeached or resign that he is "retiring from political commentary in all media venues."

Olbermann has starred in a series of online video commentaries about the Trump presidency for GQ Magazine titled "The Resistance." Olbermann said the episode released Monday would be his final one. He says the series was intended to be a temporary two-month project.

Olbermann says he has said everything he has to say on Trump and would like to enjoy some of his life again. He adds that there is "no illness, no scandal, no firing" to blame for his departure.

GQ referred to Olbermann's remarks when asked for comment on his departure.

Olbermann has previously hosted shows on MSNBC, Current TV, ESPN and Fox Sports.
