President Donald Trump appears poised to announce a two-year extension of Affordable Care Act subsidies, due to expire at the end of December, while setting new limits on who is eligible to receive the tax credits, according to reports. Without an extension of Covid-19-era Obamacare subsidies, insurance premiums for nearly 22 million American citizens threaten to more than double early next year, a point made repeatedly by Democrats during the recent 43-day government shutdown, who refused to sign a stopgap spending bill that did not address the problem.
