The leap toward a deal followed a White House meeting of a group of Republican senators hosted by President Trump. "It went really well," said Alabama Sen. Katie Britt, who was among the attendees. Asked if the group had a solution in hand, she replied "We do." Optimistic signals came from the other side of the aisle as well. "Both sides are talking in a serious way," Senate Minority Leader Chuck Schumer told the Wall Street Journal on his way out of the Capitol on Monday night. 

The crisis sprang from Democrats' refusal to fund the Department of Homeland Security unless reforms are made to how Immigrations and Customs Enforcement (ICE) officers carry out their duties. Those demands came after ICE agents shot two aggressive anti-ICE activists to death in two separate incidents in Minnesota. 

Some of the leftists' demands may actually be considered reasonable by those right-wingers and libertarians who are wary of police overreach -- such measures include refraining from forcible entry into private homes without a warrant, a ban on agents wearing masks, and the implementation of body cameras. Democrats have also demanded an end to roving patrols and additional training on use of force and de-escalation. With Republicans only holding a 53-47 margin, the Democrats have the numbers to block funding, since it takes 60 votes to get by a filibuster. 

The deal that's taking shape would fund all of the sprawling, 260,000-employee DHS except for Enforcement and Removal Operations, which is the ICE group that arrests and deports immigrants.

Money would flow to ICE's Homeland Security Investigations, which focuses on international crimes like human trafficking and drug smuggling, Democratic Delaware Sen. Chris Coons told the Journal. 

As for the next step: 

Coons and other Democrats said they expect an offer on paper from Republicans as soon as Tuesday, and the details would matter.

"Trust but verify. It's part of the challenge of our dear president," Coons said, making a roller-coaster motion with his hand.
