As House Republicans prepared to vote Tuesday on a budget blueprint that calls for ravaging Medicaid and other programs to help fund trillions of dollars in tax breaks for the wealthy, progressive lawmakers joined community members and organizers outside of the U.S. Capitol to launch a new coalition demanding a radically different approach.

“Enough with the attacks on working people in order to fund billionaire tax cuts,” Rep. Greg Casar (D-Texas), chair of the Congressional Progressive Caucus, said at a press conference. “Just tax the billionaires instead of funding the billionaires.”

Speakers at Tuesday’s event cast the “Tax the Greedy Billionaires” coalition—which includes People’s Action, MoveOn, and other advocacy groups—as a direct challenge to President Donald Trump and congressional Republicans’ legislative agenda, particularly the push for $4.5 trillion tax cuts primarily for the wealthiest Americans, financed by deep cuts to Medicaid, federal nutrition assistance, and other key programs.

“The Republican plan is about making government more efficient for big corporations and billionaires who are screwing us over,” said Casar. “We don’t need to cut Social Security; we can expand it. We don’t need to cut people’s healthcare; we can expand it. We can have a country that is better off for small businesses and workers alike.”

The press conference included remarks from organizers who warned the House GOP’s proposed $880 billion Medicaid cuts over the next 10 years would have devastating—and potentially deadly—impacts on their communities.

“Medicaid afforded me the opportunity to get on life-saving medication,” said Elissa Tierney, co-founder of an organization that helps people negatively impacted by substance addiction. “I am asking, begging: Please protect these programs.”

“If your vote is going to result in someone dying or losing their home,” Tierney added, “vote no.”

A full House vote on the budget blueprint, which Trump has endorsed, could come as soon as Tuesday evening, though there could be delays caused by divisions in the narrow Republican majority as GOP lawmakers face mounting constituent backlash in their home districts.

Politiconoted Tuesday that House Speaker Mike Johnson (R-La.) “faces some bleak arithmetic: No Democrats are expected to back the budget plan, and if all members are present and voting, he can lose only one Republican and still approve it.”

“Do not take your eye off the ball—and the ball is always the money.”

In a letter to members of Congress on Tuesday, the new coalition urged lawmakers not to “slash programs that working families depend on.”

“Tax the greedy billionaires now,” the letter adds. “The American Dream is dying in a system where unlimited wealth for the few destroys opportunity for all.”

Last month, according to an analysis unveiled Monday, the world’s billionaires saw their collective wealth surge by $314 billion—roughly $10 billion per day.

The GOP’s proposed extension of expiring provisions of their 2017 tax law would be a major boon to billionaires in the United States, who saw their wealth skyrocket in the years following the law’s enactment.

“Republicans are not thinking about regular people ever,” Rep. Becca Balint (D-Vt.) said at Tuesday’s press conference. “It’s about who’s at the top who we can give more money to while the rest of us are scrapping around for every little bit that we can get. It’s not right.”

“Do not take your eye off the ball—and the ball is always the money,” Balint added. “Who has the money, who’s getting the money, and how are the rest of us being screwed.”
