President Donald Trump took a swipe at the late Rep. John Dingell during his raucous impeachment-day rally on Wednesday, drawing a quick rebuke from the longtime Michigan congressman’s widow and successor in the House. Trump told the Battle Creek rally that Debbie Dingell had thanked him profusely for providing “A-plus treatment” after her husband’s death in February, including ordering flags flown at half-staff. John would be so thrilled.
