In March 2012 the "Marine Corps Times" reported that navy officials were reviewing new evidence related to Peralta's case, including two videos (one by Marine combat photographer Steve Sebby) and a pathology report. The evidence was provided by California Representative Duncan D. Hunter, who served with 1st Battalion, 11th Marines during Operation Vigilant Resolve (the first battle for Fallujah). In December 2012 the Department of Defense announced that the Navy Cross would not be upgraded, with Secretary of Defense Leon Panetta saying that he did not want to overturn his predecessor's decision. Hunter said he would appeal, introducing a resolution co-sponsored by fellow California Representative Xavier Becerra which recommended that Peralta receive the Medal of Honor. When Chuck Hagel replaced Panetta as Secretary of Defense, Hunter hoped he would be more receptive to the new evidence. However, in February 2014 Hagel announced that Peralta's Medal of Honor nomination would not be reconsidered. In June 2015 Peralta's mother, Rosa Maria, received the Navy Cross at a Camp Pendleton ceremony.
