As President Joe Biden gears up to press Congress for a $3 trillion overhaul of the nations infrastructure , Republicans have started trying to narrow the packages ambitions to just roads, bridges and ports.

On Monday, Biden will face some new pressure on the package, but from the left. Much of the Congressional Progressive Caucus is set to unveil the THRIVE Act, which would provide $10 trillion in federal infrastructure spending over the next decade, including massive investments in renewable energy, zero-emissions buildings and economic development in some of the worst-polluted parts of the country.

The THRIVE Act is the agenda that establishes the pillars for economic renewal in our country, Sen. Ed Markey (D-Mass.), a lead sponsor of the Senate version of the bill, told HuffPost by phone. This bill lays out a plan for massive job creation within the United States, so that a younger generation of Americans can think of these jobs as careers.

It seems likely that Democrats will be able to get some level of infrastructure through both chambers; even Sen. Joe Manchin (D-W.Va.), the most conservative Democrat in the Senate and a powerful swing vote, has signaled willingness to pass an infrastructure bill without Republican support. And Biden appears to be warming to calls to reform or scrap the filibuster, the Senate procedure requiring a 60-vote majority to pass most legislation. But the THRIVE Act a version of which former Rep. Deb Haaland (D-N.M.), who now serves as Bidens interior secretary, introduced last year offers a broad progressive consensus on what an ambitious package should include.
