Error-ridden state reviews have purged millions of the poorest Americans from the Medicaid program in recent months. Poverty experts are questioning if the Biden administration is doing enough to stop states from wrongly removing people from the government health care program. Estimates show up to 30 million people could be dropped from Medicaid as states finish reviewing their rolls over the next year. Advocates interviewed around the country say problems with the government forms, websites and phone lines in states including Texas, Florida, North Carolina and Arkansas have led to the high number of people losing Medicaid. Arkansas' Department of Human Services says it tried to reach people with additional calls, emails and texts.
