In this photo taken Tuesday Oct. 2, 2012, Paul Chavez, Cesar Chavez's middle son and president of the Cesar Chavez Foundation stands near his father's grave site in the memorial garden in Keene, Calif. Today, the foothills of the Tehachapi mountains continue to house the United Farm Workers of America headquarters and memorials to Chavez, though farmworkers no longer live there. President Obama is designating parts of the property as a national monument and visiting the site on Monday, a move seen as likely to shore up support from Hispanic and progressive voters just five weeks before the election.
