Former Vice President Joe Biden called for President Trump's impeachment and removal from office, on Wednesday.

Up until now, Biden had reserved judgment, saying he supported the House's impeachment inquiry and wanted to see what the facts showed.

But in a campaign speech in Rochester, N.H., Biden was unequivocal, saying that "to preserve our Constitution, our democracy, our basic integrity, [Trump] should be impeached."

Biden said the case was already clear before the public.

"With his words and his actions, President Trump has indicted himself. By obstructing justice, refusing to comply with the congressional inquiry, he's already convicted himself," Biden said. "In full view of the world and the American people, Donald Trump has violated his oath of office, betrayed this nation and committed impeachable acts."

Biden later argued that "impeachment isn't only about what the president has done — it's about the threat the president poses to the nation if allowed to remain in office."
