After the House late Tuesday passed a nonbinding resolution condemning President Donald Trump's racist attacks on four Democratic congresswomen, outside progressives and lawmakers argued a "strongly worded" rebuke is not sufficient to hold the president accountable and called for impeachment hearings to begin immediately.

In a statement after the resolution passed largely along party lines—with just four House Republicans breaking from their party and joining the united Democratic caucus—CREDO Action co-director Heidi Hess said the vote "is not enough."

"Donald Trump is a racist, and it's good to see House Democrats finally calling him out for what he is," Hess said of the resolution, which condemned Trump's "racist comments that have legitimized and increased fear and hatred of new Americans and people of color."

But Hess said Democrats must go further, a sentiment that was echoed across social media:

cool now do impeachment!!!!! https://t.co/dAbnXduwnP — Talia Lavin (@chick_in_kiev) July 16, 2019 what if instead of all this shit for what’s effectively a strongly worded statement we just did impeachment instead — Ashley Feinberg (@ashleyfeinberg) July 16, 2019

"House Democrats should stand with Reps. Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib, and Ayanna Pressley when they push for greater accountability for the Trump administration," said Hess. "And they should either pass Rep. Al Green's articles of impeachment or immediately start an impeachment investigation in order to use all the power they have to try to remove a racist from the White House."

Shortly following the passage of the nonbinding resolution Tuesday night, Green, a Democrat from Texas, introduced new articles of impeachment against the president—a move that was reportedly met with opposition by the Democratic leadership, including House Speaker Nancy Pelosi (D-Calif.).

"To condemn a racist president is not enough, we must impeach him," Green said in a statement. "This will be a defining vote. The world is watching, and history will judge us all."

Green read his impeachment resolution in full on the House floor late Tuesday:

Donald John Trump has, by his statements, brought the high office of the president of the United States in contempt, ridicule, disgrace and disrepute, has sown discord among the people of the United States, has demonstrated that he is unfit to be President, and has betrayed his trust as president of the United States to the manifest injury of the people of the United States, and has committed a high misdemeanor in office. Therefore, Donald John Trump, by causing such harm to the society of the United States, is unfit to be president and warrants impeachment, trial and removal from office.

As the Washington Post reported Tuesday, "Green's move will force House Democrats to deal with the [impeachment] issue in the near term because of the privileged nature of the resolution."

"Under House rules," according to the Post, "Democratic leadership can decide to try to table the impeachment articles, effectively killing them for now and risk criticism from the party's liberal base; refer them to the House Judiciary Committee for possible consideration; or allow the vote to proceed. If leaders do nothing, Green can force a vote on the impeachment articles in two legislative days."

Green's impeachment resolution comes just 24 hours after the four Democratic congresswomen targeted by Trump's racist tweets said during a press conference that they will not be baited by the president's attacks and reiterated their support for impeachment.

"I have not made impeachment central to my election or my tenure," said Omar, a Minnesota Democrat and Somali refugee who Trump has singled out for particularly vile abuse. "But since the day that I was elected, I've said to people it is not if he will be impeached, but when. It is time for us to stop allowing this president to make a mockery out of our Constitution. It is time for us to impeach this president."

Tlaib, a Democrat from Michigan, echoed Omar, aiming her message at Democratic leaders.

"I urge House leadership, many of my colleagues, to impeach this lawless president," said Tlaib.

In a tweet following the House vote Tuesday night, The Nation's John Nichols expressed agreement with calls for Democrats to do more than pass a nonbinding condemnation of the president.

"The House vote to criticize Trump for being a scorching racist was fine," said Nichols. "But I would prefer to impeach Donald Trump now."

"There is no question that Donald Trump should be impeached and removed from office," Nichols wrote in a column this week. "Nor is there any question that, as Rashida Tlaib reminds us, presidential racism is an appropriate place of beginning for the accountability moment that this country so desperately requires."
