Incoming House Speaker Nancy Pelosi (D-CA) told NBC’s Savannah Guthrie that she wouldn’t decide one way or another on beginning impeachment proceedings against President Donald Trump until special counsel Robert Mueller finishes his investigation.

She agreed that impeachment would be a “sad and divisive” thing for the country and added that “we shouldn’t be impeaching for a political reason, and we shouldn’t avoid impeachment for a political reason.”

Later on Thursday, Democrats will retake the House majority, endowing them with the power to pass articles of impeachment. However, the GOP still enjoys a majority in the Senate, making it unlikely that Trump would be convicted and booted from office.

Pelosi also said that current DOJ precedent that a sitting President cannot be indicted should be an “open discussion in terms of the law.”
