The U.S. Department of Labor is telling states they have to combat fraud, waste and abuse in their unemployment insurance programs. And if they don't, they could face having federal administrative funds withheld. The warning to states on Wednesday was the latest in a line of announced actions addressing fraud in state-run programs that use federal money. Like others, this announcement focused on allegations of problems in states where Democrats control the governments. The department did not explain the source of those allegations. It said that states would receive further directives in coming weeks.
