Senate Democrats plan to forge ahead with crafting a massive infrastructure package next month — regardless of whether Republicans get on board — as they push to pass a bill this summer.

Senators will be out of Washington next week for the Memorial Day holiday. When lawmakers return, Democrats aim to write an infrastructure plan that touches on everything from transportation to broadband, utilities and job training.

“As the President continues to discuss infrastructure legislation with Senate Republicans, the committees will hold hearings and continue their work on the Build Back Better agenda – with or without the support of Republican Senators,” Senate Majority Leader Chuck Schumer, D-N.Y., wrote in a letter to Democrats on Friday. “We must pass comprehensive jobs and infrastructure legislation this summer.”

President Joe Biden has worked with Senate Republicans to see if they can strike a bipartisan deal to revamp American infrastructure. After the latest back-and-forth in their talks, the sides appear far from an agreement on what should go into a bill and how the government should pay for it.
