On Thursday, President Trump signed an executive order to unwind parts of the Affordable Care Act. Trump promised on Tuesday to use "the power of the pen" to tackle ObamaCare, since Congress hasn't. His executive order directs federal agencies, notably the Labor Department, to relax rules on coverage and benefits under smaller businesses that band together to buy insurance as an association and short-term insurance plans. The goal is to leave consumers with more options, including lower-cost plans that don't cover as much. Health-insurance experts warn that the order will likely undermine the federal markets in such a way that insurance could become prohibitively expensive for older and sicker people, including those with pre-existing conditions.
