A new bipartisan group of rank-and-file senators has formed to discuss how to end the weeks-long government shutdown, with talks between congressional leaders and the White House at a standstill.

But unless President Trump and Democratic leaders find common ground, it’s unclear what the rank-and-file talks could yield, and even some participants were downbeat after the group held its first meeting late Monday afternoon in the basement of the Capitol. About a dozen lawmakers were in attendance, split between Democrats and Republicans.

“I sat there for an hour and didn’t know what the hell it was about,” said Sen. Joe Manchin III (D-W.Va.).

Manchin said that “nothing seems to be working” to bring an end to the partial government shutdown over Trump’s demands for money for his border wall.

“Well I think what’s important is to recognize that you’ve got a bipartisan group of folks that are very focused on forging a path through the wilderness,” said Sen. Lisa Murkowski (R-Alaska), who has called for the government to be reopened while the dispute over Trump’s wall money is hashed out. “We’re not just going to sit back and do nothing.”

With the shutdown entering its fourth week, Trump remains dug in on his demands for $5.7 billion to build hundreds of miles of new walls along the U.S.-Mexico border. Democrats are refusing to give him anywhere near that amount.

An effort last week led by Sen. Lindsey O. Graham (R-S.C.) collapsed after Vice President Pence announced publicly that Trump wasn’t interested in a deal involving trading wall funding for protections for unauthorized immigrants brought to the United States as children.
