Sen. Lindsey Graham is throwing a Hail Mary to reopen the government.

Graham brought together a half dozen Republican senators Wednesday afternoon in a last-ditch attempt to resolve the three-week stalemate before President Donald Trump deploys an explosive emergency declaration to build his border wall. The Republican senators were joined mid-meeting by White House emissaries Jared Kushner and Shahira Knight, the president’s congressional liaison.

Democrats were not invited to participate in the meeting, which largely comprised of centrist Republicans, including Sens. Rob Portman (R-Ohio) and Susan Collins (R-Maine). The participants emphasized that the discussions were preliminary in nature, but some of these senators are scheduled to meet Thursday with Senate Majority Leader Mitch McConnell to continue the discussions, according to congressional sources.
