Remember how tax information about Senate candidate Christine O'Donnell was leaked during the 2010 campaign?

Well, it turns out that the leak came from within the IRS.  How much worse does it get than using IRS information to attack political opponents who are running for the US Senate?

. . . The phone message earlier this year shocked the battled-scarred candidate, a tea party favorite who knocked off Republican mainstay Michael Castle in the primary before losing in a bid to win Vice President Joseph R. Biden’s former seat. 

“Ms. O'Donnell, this is Dennis Martel, special agent with the U.S. Department of Treasury in Baltimore, Md. … We received information that your personal federal tax info may have been compromised and may have been misused by an individual,” he said in the January message left on her cellphone. 

For Ms. O'Donnell, the message immediately raised red flags. 

On March 9, 2010, the day she revealed her plan to run for the Senatein a press release, a tax lien was placed on a house purported to be hers and publicized. The problem was she no longer owned the house. The IRS eventually blamed the lien on a computer glitch and withdrew it. 

Now Mr. Martel, a criminal investigator for the Treasury Department’s inspector general for tax administration, was telling her that an official in Delaware state government had improperly accessed her records on that very same day. . . .
