On Wednesday, [Trump's] guests were health-care executives — many of whom represent companies or institutions that have a big stake in the outcome of Trump's ambitions to dismantle the Affordable Care Act. According to a pool report, the group, all men, met with him at 11 a.m. at the Mar-a-Lago estate in Palm Beach, Fla. They included John Noseworthy of the Mayo Clinic, Paul Rothman of Johns Hopkins Medicine, David Torchiana of Partners HealthCare and Toby Cosgrove of the Cleveland Clinic.
