President Trump said Wednesday that he will sign an executive order allowing people to buy health insurance across state lines — a move that would expand consumers’ options and possibly lower costs.

Trump called it a “very major” executive order that he would probably sign next week, so that “ people can go out across state lines, do lots of things, and buy their own healthcare.”

Kentucky Sen. Rand Paul first revealed Trump’s plan — long championed by conservatives as a market-based fix that would increase competition — on MSNBC Wednesday morning.

“I think there’s going to be big news from the White House in the next week or two, something they can do on their own,” Paul said.

Trump, he added, “can legalize on his own the ability of individuals to join a group or a health association across state lines and buy insurance.”

The president, speaking to reporters on the South lawn of the White House as he prepared to departing to Indianapolis to deliver a speech on tax reform, also insisted that Republicans “have the votes” on healthcare reform despite the Senate’s latest failure to pass a bill to repeal Obamacare.

He predicted another vote in January, February or March and said that, in the meantime, he would negotiate with Democrats on a bipartisan bill.
