ST. PAUL, Minn. (AP) — Minnesota is joining a lawsuit over President Donald Trump's decision to stop federal payments to insurers that had helped hold premiums down for people buying insurance under the Obama-era health care law.

The White House announced late Thursday it would end the payments after months of speculation. States are preparing for premium spikes of 20 percent or more in the individual market.

Minnesota Attorney General Lori Swanson says cutting off the payments will make the cost of health care much worse for thousands of Minnesotans.
