Updated 5/31, 12:50 p.m.More Democrats are backing impeachment proceedings against President Donald Trump after Special Counsel Robert S. Mueller III delivered a statement Wednesday on his report on investigation into Russian meddling in the 2016 election. Three presidential candidates — Sens. Kamala Harris, Cory Booker and Kirsten Gillibrand— joined the pro-impeachment caucus this week even as House Speaker Nancy Pelosi has tried to quiet the growing call in her party.Mueller said in a news conference Wednesday that while the Justice Department cannot indict the president, “the Constitution requires a process other than the criminal justice system to formally accuse a sitting President of wrongdoing”: impeachment.Twenty-seven Democrats voiced support for impeachment before Mueller’s resignation; at least 10 more backed impeachment by Thursday morning. There are concerns among House Democratic leaders that impeachment could prove divisive and imperil Democrats in battleground districts next year. But some leaders in the caucus have pressed the speaker on the matter, including House Judiciary Committee Chairman Jerrold Nadler, the panel with jurisdiction over impeachment. Democrats who favor initiating impeachment proceedings point out it will strengthen their legal standing as they grapple with Trump’s resistance to their investigations, including his defiance of their subpoenas. Others say it is a constitutional duty of the legislative branch to properly oversee the executive.
