Most of the members who support an impeachment inquiry are liberal. They include much of the Congressional Progressive Caucus leadership as well as 17 members of the Congressional Black Caucus (CBC), whose members have long been among the most outspoken on impeachment.

Half of the members of the House Judiciary Committee, which would be charged with impeachment proceedings, already support launching an inquiry.

One of the most vocal advocates in the House has been Rep. Al Green Alexander (Al) N. GreenThe Memo: Trump's race tactics fall flat Trump administration ending support for 7 Texas testing sites as coronavirus cases spike The Hill's Coronavirus Report: Miami mayor worries about suicide and domestic violence rise; Trump-governor debate intensifies MORE (D-Texas), who forced two floor votes on his articles of impeachment in 2017 and 2018.

The articles of impeachment from Green, a CBC member, accused Trump of stoking racial divisions in America.

“At some point we will have to say the word 'impeachment' if we're going to get to impeachment. And I hear people saying that the president should be impeached. So it shouldn't be a difficult thing to say, and hopefully we'll get to it,” Green said.

Just under two-thirds of Green’s CBC colleagues supported his articles of impeachment on the House floor in the last Congress. The bitter feelings toward Trump among black lawmakers began long before the president even took office — when he raised doubts about whether then-President Obama was born in the U.S.

And it’s only gotten worse since Trump engaged in racial controversies such as casting equal blame on white supremacists and counterprotesters for the 2017 violence in Charlottesville, Va., as well as personally attacking multiple members of the CBC.

“Given where the CBC historically has been with respect to this president, we have been the No. 1 company that he rejects.

But half of his committee’s members — many of whom are in safe liberal districts — are already on board with the idea.

California, one of the bluest states in the country, has many pro-impeachment voices.

But she indicated that it’s on her mind.

“To tell you the truth, I have been thinking more and more about when it would be appropriate to start the inquiry,” Mucarsel-Powell told CNN’s “New Day” on Friday.

“I've read [special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE's] report. There is clear evidence that this president has obstructed justice, and I think that there have to be serious consequences,” she added.

Greg Stanton Gregory (Greg) John StantonUS Chamber of Commerce set to endorse 23 House freshman Democrats Arizona lawmaker warns Pence state may end coronavirus testing due to shortage Sanders poised for big Super Tuesday MORE (D-Ariz.), won his race by more than 20 points last fall but represents a district that’s been targeted by the GOP in recent years. He’s already on board with an impeachment inquiry.

“I accept that this conclusion will be unpopular with some, but it is the right thing to do,” Stanton said.

And while the nearly 60 House Democrats publicly supportive of impeachment represent only about a quarter of the 235-member caucus, Huffman said he’s heard privately from colleagues who are more are on board than they’re letting on.

“I know the number’s higher,” Huffman said. “But many members don't want to get ahead of leadership. And so that's the delicate process that is underway.”
