Senior politics reporter Aaron Blake talks with The Washington Post’s chief correspondent covering national politics, Dan Balz, and national security reporter Abigail Hauslohner about new reporting this week about Defense Secretary Pete Hegseth. Hegseth’s continued use of Signal, an unclassified messaging app, to share highly sensitive information has roiled the agency he oversees. They also unpack new polling that shows warning signs for Trump: public support for his legally dubious immigration policies have turned negative. Today’s show was produced by Laura Benshoff with help from Rennie Svirnovskiy. It was edited by Lucy Perkins and mixed by Sean Carter. Subscribe to The Washington Post here.
