Senate Majority Leader Chuck Schumer told Democratic colleagues Monday that this legislative session has led to moments of “deep discontent and frustration” as the Build Back Better Act hangs in limbo, blaming Sen. Joe Manchin, D-W.Va., for not coming “to an agreement” with President Biden, while maintaining that the caucus will continue to “try to find a way forward” on the president’s economic agenda.

In a letter to Democratic colleagues Monday morning, Schumer, D-N.Y., reflected on the first session of the 117th Congress — which he pointed out “began with Republicans in the majority but quickly switched to Democratic control by the slimmest margins and has become the longest 50-50 Senate in history.”

“We should be proud of our accomplishments,” Schumer wrote. “We should also be determined to finish the work that remains undone.”
