“It is impossible to ignore the mounting evidence that President Trump has repeatedly broken the law, committed impeachable offenses, and continues to obstruct justice. The Congressional Progressive Caucus strongly endorses the House Judiciary Committee's current formal impeachment investigation and the adoption of the Resolution of Investigative Procedures,” the CPC said in a statement.

“Our duty is to uphold the Constitution and we must do all we can to protect our democracy,” it added.

The CPC has 98 members, making it the second-biggest Democratic caucus.

The statement comes after House Judiciary Committee Chairman Jerrold Nadler Jerrold (Jerry) Lewis NadlerDemocrats shoot down talk of expanding Supreme Court Schumer: 'Nothing is off the table' if GOP moves forward with Ginsburg replacement Top Democrats call for DOJ watchdog to probe Barr over possible 2020 election influence MORE (D-N.Y.) announced Monday that his panel will vote this week on its procedures for hearings as it continues to weigh articles of impeachment against the president.

Those areas include Trump’s alleged floating of pardons to border and law enforcement officials, payments made to women alleging affairs with the president, and whether the president profited from government spending at his family-owned properties during official trips.

While a majority of the Democratic House delegation has voiced support for impeachment in some form, some, including the CPC, appear to hew in favor of an investigation into impeachment rather than a formal impeachment inquiry that requires a vote in the House.

The party’s leadership has maintained its position against formal impeachment, arguing that any effort beyond Nadler’s investigation to remove Trump from office remains publicly unpopular and would fail to pass the GOP-controlled Senate.

House Democratic leadership also worries a formal impeachment could galvanize the president’s base and may endanger moderate members in swing districts where impeachment is particularly divisive.
