Keith Olbermann will be allowed to resume his nightly program on MSNBC on Tuesday, the channel’s president said Sunday night, after he was suspended for donating money to three Democratic candidates.

The policy at MSNBC’s parent, NBC News, says journalists cannot make political contributions without permission from the head of the news division. “After several days of deliberation and discussion, I have determined that suspending Keith through and including Monday night’s program is an appropriate punishment for his violation of our policy,” the MSNBC president, Phil Griffin, said in a statement. “We look forward to having him back on the air Tuesday night.”

Mr. Olbermann has declined interview requests since Friday, and he did not immediately confirm that he would resume his program, “Countdown,” as of Tuesday. But on Sunday afternoon, he posted to Twitter a thank-you to fans for “support that feels like a global hug.”
