Those 800,000 federal workers impacted by the shutdown are back at work today. But the threat of another shutdown looms. Democrats and Republicans have three weeks to hammer out some kind of deal on border security before funding from the short-term spending legislation runs out. President Trump said if there’s no money allocated for his border wall he’s willing to endure another shutdown or declare a national emergency so that he can use Defense Department funds to build the wall. Neither option is particularly attractive for the President. After getting nothing in the record-breaking shutdown that just ended, Trump’s GOP allies may be less likely to go down that path again. And declaring a national emergency would spark a constitutional battle that could be tied up in the courts for months.
