TAXING ISSUE - A D.C. Circuit three-judge panel—Patricia Millett, David Tatel and Neomi Rao—today will hear arguments in President Trump’s quest to stop a House subpoena issued against his longtime accounting firm Mazars USA. Trump’s lawyers at Consovoy McCarthy lost their bid in the trial court. This morning’s arguments in Washington will mark the first time an appeals court has weighed a House subpoena seeking Trump-related financial information. The Second Circuit will take up a related dispute in August.

CROOKS - A spate of hacks has plagued municipalities recently. Victoria Hudgins reports on cyber attacks against five local governments that have shut down or significantly disrupted their agencies’ work.

TRAUMA - Columbia law professor Elora Mukherjee is due on Capitol Hill today to testify before the House Committee on Oversight and Reform on what she and fellow investigators found last month when they visited a detention facility housing hundreds of migrant children in Clint, Texas. That visit—and subsequent media reports—touched off a public outcry over conditions in the border camps. Karen Sloan reports that Mukherjee, who heads Columbia’s Immigrants’ Rights Clinic, offers disturbing details in her 33-page written testimony submitted ahead of the hearing, including young children too traumatized to tell investigators their names.
