Senate Majority Leader Chuck Schumer (D-NY) voiced optimism on Tuesday that the Senate can reach a deal on border security even as he acknowledged that talks had stalled.

A bipartisan working group negotiating changes to immigration law hoped to announce a deal as senators returned from the Christmas recess, yet Sen. James Lankford (R-OK), the lead Republican negotiator, told reporters on Monday evening there were “too many unresolved parts” for an agreement to materialize this week.
