"On Wednesday, President Trump revealed profound confusion about how health insurance works, suggesting to the New York Times that he thinks people can buy coverage for $12 a year. Asked about Trump’s comments during an MSNBC interview Thursday morning, Sen. Bill Cassidy (R-LA) defended the president, saying he’s “about broad principles,” not specifics. But Cassidy — who publicly expressed concern about the version of Trumpcare that went down in flames earlier this week, and has proposed his own replacement plan — took things a step further. He went on to say that he doesn’t think it’s important for the president to understand the details health care legislation at all."
