The top human resources official at the U.S. Department of Veterans Affairs resigned a day before the scheduled release of an inspector general’s report on questionable spending tied to two conferences in Florida. The agency announced in a brief statement yesterday that Secretary Eric Shinseki had accepted the resignation of John Sepulveda, the VA’s assistant secretary for human resources. The department’s inspector general plans to release its report at 3 p.m. Washington time today following a probe into the two VA events held last year, Catherine Gromek, a spokeswoman for the watchdog office, said in a Sept. 28 e-mail.
