SPRINGFIELD — A former top state transportation employee has been fined $4,000 in connection with a summer job hiring scandal at the Illinois Department of Transportation.

Danny Clayton, who was removed from his $102,000 post as assistant regional engineer in the agency’s District 9 Carbondale office nearly two years ago, was found by the state’s executive ethics commission to have violated state ethics law.

He could not be immediately reached for comment Monday.

At issue were allegations that Clayton tampered with tests used to grade potential employees of a 2009 summer jobs program. Investigators suggested Clayton may have altered scores or asked applicants to take tests a second time to boost their results.

Clayton also was found to have attempted to convince a co-worker to lie about the scandal to investigators.

That employee, Michael Bigler, blew the whistle on Clayton and told investigators he was being pressured by Clayton to cover up the tampering.

Bigler had no comment Monday.

Clayton, of Harrisburg, began working at IDOT in 2003 during former Gov. Rod Blagojevich’s first year in office.

As assistant regional engineer, Clayton oversaw the administration of IDOT in the state’s 16 southernmost counties.
