A top EPA official plans to resign, just three weeks after Republican Sen. David Vitter questioned him over the use of a personal email account to conduct “official business.”

EPA spokeswoman Alisha Johnson confirmed to FoxNews.com that Region 8 Administrator James Martin plans to resign effective Friday. She said it was “for personal reasons.”

Martin was facing questions about his use of personal email, as former EPA boss Lisa Jackson also comes under scrutiny for using alias emails to communicate with employees.

The agency reportedly is disputing the notion that Martin’s resignation had anything to do with the email controversy.
