Clinton, whom Trump defeated in the 2016 election, also called for the release of an unredacted version of Mueller’s report. “I’m really of the mind that the Mueller report is part of the beginning. It’s not the end,” she said.

“Every American who cares about holding our adversaries accountable, looking to prevent what happened from ever happening again, should take the time to go through,” she added.

As more high-profile Democrats call for impeachment proceedings against Trump, Clinton emphasized that the process should “be something undertaken in a really serious, diligent way, based on evidence.”

“I have a weird personal history about impeachment,” she said, referring to her time as a staff attorney for the House Judiciary Committee during the Watergate investigation. “It shouldn’t be a preordained conclusion. It should be based on evidence, not on partisan advantage.”

Nixon resigned before he could be impeached. Clinton’s husband, Bill Clinton, was impeached during his second term as president, but was not removed from office.

Sen. Elizabeth Warren of Massachusetts has called on elected officials to begin impeachment proceedings, along with other 2020 Democratic candidates including Sen. Kamala Harris of California and Rep. Seth Moulton of Massachusetts.

Meanwhile, Trump has railed against calls for his impeachment. He wrote on Twitter on Monday that “Only high crimes and misdemeanors can lead to impeachment.”

“There were no crimes by me (No Collusion, No Obstruction), so you can’t impeach,” Trump said.
