They worked out a deal last week with $1.8 billion for border security. Drumpf said he'd sign what they worked out, and then he reneged.
Even McConnell stated he couldn't figure out what Drumpf wanted. So there's that.
You should also pay attention to the fact that Claire McCaskill (who did vote to keep the government open) offered a bill to keep the military funded.. And Mitch shot it down. So there's also that.
