U.S. senators said on Sunday the White House has not been forthcoming with details about the military's presence in Niger after the deaths of four soldiers there earlier this month and they want more answers on U.S. operations in the West African country.
Republican Sen. Lindsey Graham and Democratic Senate leader Chuck Schumer said in separate interviews that they support Republican Sen. John McCain's effort to get answers from the Pentagon on the ambush and more broadly on the U.S. fight against ISIS in Niger.
Graham and Schumer said they had been unaware of the large U.S. presence in the country and said Congress needs more information on what could become a long and open-ended involvement.
