NBC 5 has learned Congressman Luis Gutierrez will announce Tuesday he is not running for re-election after 24 years on Capitol Hill, sources say. Guitterez telephoned key democratic leaders late this afternoon to let them know of his plans. Calls to Guitterez tonight have not been returned. Already printing petitions Monday night-- to begin the process of getting signatures before next Monday's deadline -- is Cook County Commissioner Jesus Chuy Garcia. Ald. Carlos Ramirez Rosa is considering a congressional race. This will also leave an opening on the county board should Garcia opt for Guitterez's seat.
