Good Tuesday morning. I'm Anna Palmer and welcome to your Politico Playbook audio briefing.

Stay tuned after the show for a message from Walmart.

And I'm Jake Sherman. We're entering day 18 of the government shutdown and the White House is trying out a new strategy tactically and rhetorically as this government shutdown barrels on without any sign of ending.
