The problem may be worse than first thought for the state's welfare agency.
The number of applications has increased since December.
A denver district judge ordered the agency to reduce the backlog of applicants by 40 percent by the end of this month.
At the time, more than 29,300 cases were pending. But now, the state has an additional 400 cases.
The backlog was caused in September when the agency rolled out a new computer system called Colorado Benefits Management System. The system slowed payments to the state's 600,000 recipients.
