Law enforcement officials revealed Monday that the FBI had searched the home of the son of a Democratic state lawmaker in Tennessee over the weekend, searching for evidence that would link him to the hacking of Republican vice presidential candidate Sarah Palin's personal e-mail account.

The young man, David Kernell, 20, is the son of state Rep. Mike Kernell, a Memphis Democrat and chairman of Tennessee's House Government Operations Committee. Mike Kernell denies having any involvement in the hacking, stating:

"I had nothing to do with it, I had no knowledge or anythin. I was not a party to anything of this nature at all. I wasn't in on this - and I wouldn't know how to do anything like that."

Last week a hacker broke into a personal Yahoo e-mail account of Sarah Palin, exposing some of her e-mails as evidence of the hacking. The McCain campaign confirmed the break-in, labeling it a "shocking invasion of the governor's privacy and a violation of law."

Following the break-in of Palin's account, a person claimed responsibility and published a detailed chronology of the hacking on the 4Chan website that the break-in was first revealed on. The e-mail address associated with the person who published the chronology is one that has been linked publicly to David Kernell.

The FBI and Secret Service are still investigating. The Justice Department confirmed Monday that the FBI conducted "investigative activity" late Saturday and early Sunday Knoxville related to the case. David Kernell is an economics major at the University of Tennessee, and is staying in Knoxville.
