US President Barack Obama has signed a defensce spending Bill despite his strong objections over its provisions limiting the government from bringing terrorism suspects held at Guantanamo Bay to the United States for trial in federal court. In a statement Friday, Obama said the new restrictions, in his words, ‘undermine our nation's counter-terrorism efforts.’ He said he signed the Bill because it contained important funding for military efforts. But Obama said he would ask Congress to repeal the provisions regarding Guantanamo detainees. He said he would oppose any effort to renew the restrictions when they expire at the end of the 2011 fiscal year, on September 30.The new restrictions ban the President from moving any prisoners from Guantanamo Bay to US soil for prosecution in a civilian court, and prohibit the transfer of prisoners to foreign countries without the approval of the Secretary of Defence.
