CHICAGO (AP) -- Northwestern University says files auctioned from storage units connected to ousted Illinois Gov. Rod Blagojevich include confidential attorney-client documents.

University librarian Jeffrey Garrett said Wednesday that no files will be released until official processing. The items were auctioned after Blagojevich's campaign fund stopped paying storage fees.

Illinois Attorney Registration and Disciplinary Commission spokesman James Grogan says an attorney who abandons client files may be disciplined.

Blagojevich's publicist Glenn Selig says the former governor did not know specifically what had been in storage. He declined to address any attorney-client issues.

Blagojevich was convicted this month of lying to the FBI and likely faces a retrial on 23 other counts.
