President Donald Trump on Tuesday hinted on Twitter that he’s getting closer to signing an executive order that could erode Obamacare, after Republicans in Congress failed to pass a repeal bill.

The Wall Street Journal reported on Saturday, citing an administration official, that an executive order regarding association health plans would be signed this week. The official echoed the president’s Sept. 27 comments to reporters, when he said he would “be signing a very major executive order where people can go out, cross state lines, do lots of things and buy their own health care.”

An order allowing association health plans would give Americans in the individual market who don’t receive government subsidies another health care option outside of the Affordable Care Act. About 83 percent of the 12.2 million people covered by Obamacare health plans get subsidies that help them pay their premiums, according to the U.S. Centers for Medicare and Medicaid Services.
