WASHINGTON, Nov 19 (Reuters) - U.S. President-elect Barack Obama’s top choice to lead the U.S Department of Homeland Security is Arizona Gov. Janet Napolitano, CNN reported on Wednesday, citing multiple sources.

The Democratic governor, a supporter and campaigner for Obama’s presidential campaign, had been reported to be on a short list of people to fill cabinet posts in the new administration.

CNN also reported that Chicago businesswoman Penny Pritzker was Obama’s pick for commerce secretary. (Reporting by JoAnne Allen, editing by Anthony Boadle)
