Earlier this week, however, the state’s congressional delegation demanded the state fix its system. In a letter to Hogan, U.S. Sens. Ben Cardin and Chris Van Hollen said they hear daily from constituents who continue to encounter problems. U.S. Reps. Steny Hoyer, C.A. Dutch Ruppersberger, John Sarbanes, Kweisi Mfume, Andy Harris, Anthony Brown, Jamie Raskin and David Trone also signed the letter, saying that problems include errors processing weekly certifications, performance issues with the benefits website and inaccurate denials of benefits.
