From this, via this:

Ohio's inspector general is investigating why a state agency director approved checking the state child-support computer system for information on "Joe the Plumber."

Helen Jones-Kelly [sic], director of the Ohio Department of Job and Family Services, confirmed today that she OK'd the check on Samuel Joseph Wurzelbacher following the Oct. 15 presidential debate.

She said there were no political reasons for the check on the sudden presidential campaign fixture though the Support Enforcement Tracking System.

Amid questions from the media and others about "Joe the Plumber," Jones-Kelley said she approved a check to determine if he was current on any ordered child-support payments...

"Our practice is when someone is thrust quickly into the public spotlight, we often take a look" at them, Jones-Kelley said, citing a case where a lottery winner was found to owe past-due child support. "Our practice is to basically look at what is coming our way."

Just a gentle "looking". She may have some minor link to BHO or at least has shown herself to be a supporter; see the second link. She donated $2,300 to the Obama campaign in July 2008.

Bear in mind that if BHO becomes president he's going to stock the permanent government with plenty of people who'll take a "look" at BHO's opponents.
