Post Politics Now: Biden to speak on health-care access after a win for abortion rights in Kansas

They have actively engaged Sinema in private negotiations in recent days, opening the door for possible revisions to the health-care and climate-focused bill known as the Inflation Reduction Act.

Publicly, Sinema has said nothing about the measure, and her aides maintain she is still reviewing it. Behind the scenes, though, the senator has spoken with Democrats about at least two of the proposal’s tax provisions, according to two people familiar with the matter who spoke on the condition of anonymity to describe the sensitive negotiations.

The first involves tightening a policy that benefits hedge fund, private equity and real estate managers by taxing much of their compensation at a lower rate than most other earned income. The second sets a minimum tax on large, profitable companies that pay nothing to the U.S. government. On both, Sinema’s exact requests are unclear, though she previously has expressed some openness to a minimum corporate tax.
