But progressive Democrats in the House, eager to make good on campaign promises ahead of the 2022 midterms, could pose a new set of hurdles to the bipartisan infrastructure plan. 

Progressives aren’t expected to make dramatic changes to the infrastructure bill, but they insist that the Senate first pass a separate $3.5 trillion bill focused on poverty, climate change and health care.

The House is expected back from its recess Sept. 20.

The infrastructure proposal is the product of months of haggling between Republicans and Democrats and includes more than $500 billion above projected federal spending on upgrading the country’s transportation systems.
