Examiner Editorial: Lengthy Senate report details EPA FOIA abuses

Jackson resigned from EPA in December 2012 after it became known the agency's inspector general had opened an investigation. Jackson has recently "lawyered-up," apparently as part of her preparation for the House hearing on Tuesday, according to the Washington Free Beacon.

The WFB quotes a Jackson lawyer denying that she has done anything illegal and expects to cooperate fully with the House panel.

Jackson's use of the Richard Windsor account became public last year as a result of publication of a book by Christopher C. Horner of the Competitive Enterprise Institute.
