Norwegian police officers guard City Hall, the venue for the awarding of the Nobel Peace Prize, in Oslo December 9, 2009. Two leading international human rights groups gave U.S. President Barack Obama mixed reviews on his human rights record on Wednesday, a day before he is slated to accept the 2009 Nobel Peace Prize in Oslo. Human Rights Watch and Amnesty International urged Obama to use his acceptance speech on Thursday to renew U.S. leadership on human rights after its position was undermined by abuses committed during the Bush administration's war on terrorism.
