What’s the latest on the David Axelrod email controversy?  The Hill reports that Rep. Issa is interested in investigating the issue.

“Based on reports of Americans who received this e-mail without having contacted the White House, I am concerned about the possibility that political e-mail address lists are being used for official purposes,” Issa wrote.

The White House on Monday did not immediately respond to a request for comment on Issa’s letter.

Meanwhile, Politico reports that flag@whitehouse.gov (the email address White House New Media Director Macon Phillips urged readers to send “fishy” information to) is being disable.

E-mails to that address now bounce back with the message: “The e-mail address you just sent a message to is no longer in service. We are now accepting your feedback about health insurance reform via http://www.whitehouse.gov/realitycheck.”

On the Axelrod email issue, Politico also reports that the White House announced it is changing rules on email addresses.

“We are implementing measures to make subscribing to e-mails clearer, including preventing advocacy organizations from signing people up to our lists without their permission when they deliver petition signatures and other messages on individual’s behalf,” spokesman Nick Shapiro said in a statement Sunday night.
