Several 2020 Democrat candidates called for President Donald Trump’s impeachment on Tuesday, calling him a “criminal” and demanding Congress to take action.

The renewed calls for impeachment come hours before a caucus-wide meeting with House Speaker Nancy Pelosi (D-CA), set for 4 p.m. ET. The caucus is expected to discuss whether they should formally pursue impeaching the president.

Many 2020 Democrats are emphatically expressing support.

“The President is a criminal,” Julián Castro (D) wrote. “The House must start impeachment hearings today.”

“This isn’t a partisan issue—or shouldn’t be,” Sen. Cory Booker (D-NJ) tweeted. “When the president of the United States is working with other countries to interfere with our elections, we should begin impeachment proceedings.”

“It was true when I said it in 2017 running for Senate in Texas and it’s still true today: President Trump should be impeached,” former Texas Rep. Beto O’Rourke (D) added.

Rep. Tim Ryan (D-OH) concurred, calling Trump a “classless, amoral gutter dweller.”

This President has no regard for any of the high standards that we expect from our Presidents. It disgusts me to think he sits in the same chair as Franklin Roosevelt, John F. Kennedy and Ronald Reagan. Donald Trump is a classless, amoral gutter dweller. — Tim Ryan (@TimRyan) September 24, 2019

And any Republican who wants to salvage some of the last vestiges of what used to be a noble and important political party in America should speak up for impeachment now before there isn’t a Republican Party at all. — Tim Ryan (@TimRyan) September 24, 2019

Many folks continue to demand impeachment proceedings for @POTUS, I’m on record as well. In the mean time, Americans still struggle to access healthcare, are under-employed, lack skills for this new economy & just want Washington to get something done for them but I’ve digressed. — Wayne Messam (@WayneMessam) September 24, 2019

Enough. It’s time to impeach. — Kamala Harris (@KamalaHarris) September 24, 2019

The House must impeach. It must start today. — Elizabeth Warren (@ewarren) September 24, 2019

Joe Biden (D) is also expected to float impeachment in the event that Trump does not comply with the information requests from Democrats in Congress:

Biden campaign says "he’s going to call on Trump to comply with all of Congress’ outstanding, lawful requests for information – in the Ukraine matter, and in the other investigations — and if Trump does not comply, Congress has no choice but to impeach.” — Ben Jacobs (@Bencjacobs) September 24, 2019

Some speculate that Pelosi will use accusations from the alleged “whistleblower” – who claimed Trump urged Urkanian officials to “re-open inquiries into the business dealings of former president Joe Biden’s son, Hunter Biden” – as a basis to present an impeachment resolution, although the Washington Post reports that Pelosi is “discussing the creation of a select committee to conduct the possible impeachment of President Trump”:

Confirmed: House Speaker Nancy Pelosi planning to put a resolution on the House floor tomorrow to address the Ukraine issue as there are increasing calls by Democrats to start the impeachment process for President Trump. — Yamiche Alcindor (@Yamiche) September 24, 2019
