President Donald Trump has recently twhreatened (that’s a threat communicated via Twitter) to stop payments of billions of dollars out of the federal treasury that have been going to insurance companies selling health insurance policies on the Exchanges created by the Affordable Care Act. Indeed, rumors are circulating that he may order a stop as early as tomorrow (August 1, 2017). Whether he does so this week, next week or next month, President Trump will be perfectly within his rights in stopping these illegal payments. It doesn’t matter whether these payments are “a good idea” or not or whether they actually save the federal government money.
