The special investigating committee headed by Vance on ACA fraudulent sign ups is throwing 750,000 mainly lower income enrollees for $2.2 billion savings to taxpayers. At the same time, an estimated 1.6 million people cheat on their income taxes, costing at least $300 billion annually ( one hundred times as much!!!) with some officials and analyses suggesting the total could approach $1 trillion per year). The income tax cheaters are mainly upper income people thus Republicans focus on lower income ACA cheaters. That's the Republican way.
