Maybe you should take a course in civics before you complain about nonsense. A president simply doesn’t have the authority to unilaterally dismantle a U.S. statute. Congress has to do it. Trump has done what he is able to do under our form of government. One of the first things he did was have the IRS ignore the Obamacare requirement for those tax forms that verify compliance with the individual health insurance mandate. I’m sure he will do many more things through his HHS secretary if no bill passes in Congress.
