Pentagon officials have substantiated 590 allegations of misconduct among generals, admirals and senior civilian officials from 2013 to 2017 with trends showing a steady decline in misbehavior, according to figures released Wednesday by Defense Department Inspector General Glenn Fine. Personal misconduct and ethical violations accounted for most of the violations with 277, according to the data released during a hearing of the House Armed Services Committee's personnel subcommittee. However, Fine told the panel that inappropriate relationships among senior officials with subordinates remain a cause for concern. The hearing was called in response to multiple USA TODAY reports about senior officer misconduct, said Rep. Jackie Speier of California, the subcommittee's top Democrat.
