January 21, 2009 (Washington D.C.)-- On his first day in office, President Barack Obama ordered that the U.S. prison at Guantanamo Bay be closed down within a year. Closure of the now-infamous detention facility could result in some of the 245 prisoners held there being transferred to Camp Pendleton in San Diego, according to a Pentagon study. Newly elected Congressman Duncan D. Hunter (R-Alpine) has introduced a bill, coauthored by San Diego Republican Congressmen Darrell Issa and Brian Bilbray, to block transfer of detainees from Guantanamo to Pendleton.
