With new technology came a new type of Washington scandal: missing emails.
In the latest instance, the vanished emails belonged to Lois Lerner, former head of the exempt organizations division at IRS. She's the official who oversaw the scrutiny of applicants for tax-exempt status as 501(c)(4) social welfare groups — a process that conservatives allege was meant to block Tea Party groups.
The controversy blew up just over a year ago. Lerner was pushed out of the IRS; the House cited her for contempt of Congress.
