Self-made billionaire businessman John Catsimatidis released a new commercial "Giving Back" for his run for the GOP nomination for mayor. Former Rudy Giuliani deputy Rudy Washington appears in it -- having pledged his support to Catsimatidis before former Giuliani deputy Joseph Lhota was competing with Catsimatidis for the nod. Washington, of Queens, was the highest-ranked African American in the Giuliani administration. Ex-Gov. George Pataki and ex-Sen. Serf Maltese also appear.
