The small group of conservative Democratic lawmakers that has been threatening to help Republicans halt Democrats’ budget package have raked in more than $3 million from donors in the pharmaceutical and fossil fuel industries that could see reduced profits if the plan passes.

As the House reconvenes today to tackle the budget reconciliation process, nine Democrat legislators have been promising to kill their party’s $3.5 trillion budget bill until Congress first passes a separate, smaller infrastructure spending measure, which has garnered some Republican support and which some environmental advocates say would exacerbate the climate crisis.

“We will vote against a budget resolution if the infrastructure package isn’t brought up first,” Democratic Rep. Josh Gottheimer told the Washington Post this weekend, though the American Prospect reported on Sunday that “several” of the legislators now indicated they could back down.
