PITTSBURGH (AP) — A retired Pittsburgh-area postal clerk is suing the U.S. Office of Personnel Management for a copy of his own work records as part of a fight over whether he’s been paid too much in pension benefits and owes the government a refund.

The retiree, 57-year-old Daniel Sagi, of Shaler Township, doesn’t say how much the government claims he’s been overpaid since he retired in November 2012.

But his four-page federal lawsuit says he’s filed Freedom of Information Act requests for his records four times since July and has received no response — except to acknowledge that two of his requests have been received.
