 House Republicans, meanwhile, want to talk with the President's personal physician. House Oversight Committee Chair James Comer of Kentucky sent a letter to White House physician Kevin O'Connor requesting that he appear behind closed doors for a transcribed interview with committee counsel. Comer is giving O'Connor until July 14th the contact committee staff to schedule the interview. Comer is the first House Republican to open an investigation in the wake of President Biden's debate performance and has sparked growing concerns among Democrats, including calls from a handful of House lawmakers for him to step out of the presidential race.
