The agency's new leadership has demanded the amount be repaid and Peck said he would do so.
Peck was fired as Public Buildings Commissioner after the inspector general reported some $823,000 was spent at the conference in violation of agency rules. He said he didn't condone the conduct of others but was let go because improprieties occurred on his watch.
Peck also was asked why he only approved a tepid letter to Neely for his improper travel and allowed him to receive a $9,000 bonus.
He said he acted on information he knew at the time.
