Olympic gold medalist Aly Raisman said in a CNN interview that her coach, John Geddert, "might have known" years ago about the sexual abuse by former team doctor Larry Nassar.

Why it matters: An investigation of the handling of allegations against Larry Nassar was launched on Thursday by the House Oversight Committee, after Sen. Jeanne Shaheen and Sen. Joni Ernst announced "growing bipartisan support" for such an investigation on Wednesday.
