The campaign of Democratic gubernatorial candidate Douglas Gansler on Monday called on rival Lt. Gov. Anthony Brown to make public e-mails associated with the creation of the website where consumers can buy health insurance under health reform.

Brown's offices cited executive privilege for not releasing e-mails sought in a public information request by The Baltimore Sun. The newspaper asked for e-mails between Brown and the Maryland Department of Mental Health and Hygiene and Maryland Health Benefit Exchange, the agency in charge of the health reform website.

It is unclear how many e-mails Brown is withholding. Brown was tapped by Gov. Martin O'Malley to lead the state's health reform efforts.

"Lt. Governor Brown failed and now is trying to hide behind executive privilege to avoid responsibility," Bob Wheelock, communications director for the Gansler campaign, said in a statement.

Brown could not be immediately reached for comment.
