The White House welcomed the news Thursday night that Iowa’s Republican Gov. Terry Branstad agreed to expand his state’s Medicaid program under the administration’s health-care law.

Under a compromise with the Department of Health and Human Services, the state will be allowed to charge premiums to people who earn between 100 percent and 133 percent of the federal poverty line, to pay a modest premium for health coverage.
