Talk of impeachment has been revived as the GOP moves into the majority in the U.S. House, with a left-leaning commentator warning that the House even could investigate Barack Obama's birthplace.

It's not the first time impeachment has been raised as a possibility, but this time the warning comes from Ed Schultz of MSNBC, who appeared outraged at the possibility to GOP would be in leadership in the House.

His comments:

"This is, as I've said all along on this program, about power and not governing," Schultz said. "House Republicans are promising what, subpoenas? They may even be launching an investigation into the president's birthplace. It'll be a rebirth of the birthers.

"They might go so far as to try to impeach President Obama," he said.
