Washington (CNN) Nancy Pelosi, who is poised to be the next House speaker, said that it remains open for discussion whether the Justice Department could indict a sitting president.

Ahead of the new Democratic majority taking control of the House on Thursday, the California Democratic representative was asked whether special counsel Robert Mueller should honor the Department of Justice's opinion that a sitting US president should not be indicted. Mueller is currently investigating Russian interference in the 2016 election and possible connections between President Donald Trump's campaign and the Kremlin.

Asked if Mueller could legally indict a sitting president, Pelosi said: "Let's just see what Mueller does. Let's spend our time on getting results for the American people."
