The state Department of Human Resources is trying to figure out why some 8,200 Rhode Islanders didn’t receive their state supplemental insurance payment as scheduled Monday. Officials suspect a problem with the banking transaction.

Every month some 32,000 Rhode Islanders receive a supplemental insurance payment. Typically, the recipients are disabled or elderly who didn’t work long enough to qualify for Social Security.  The state supplements the federal payments to the tune of about $40 a month. But on Monday, about 25 percent of the recipients didn’t receive the state portion.
