“Based on the overwhelming evidence of misconduct outlined in this report, Mr. Blanton must resign. He should be held accountable and reimburse the government,” said a statement issued Tuesday by six Democrats who chair committees that oversee the agency.

Sens. Patrick Leahy (D-Vermont), Jack Reed (D-Rhode Island) and Amy Klobuchar (D-Minnesota) and Reps. Rosa DeLauro (D-Connecticut), Zoe Lofgren (D-California) and Tim Ryan (D-Ohio) signed the document.
