President Obama sent additional U.S. military personnel to Niger earlier this week, bringing the total number of U.S. servicemen sent there to 100.
In a letter to Congressional leaders, Mr. Obama said the U.S. forces will facilitate intelligence sharing with the French military conducting operations in Mali, and with other partners in the region.
The U.S. military there are armed “for the purpose of providing their own force protection and security,” the president said in the letter.
“I directed this deployment of the U.S. forces in furtherance of U.S. national security interests, and pursuant to my constitutional authority to conduct U.S. foreign relations and as command-in-chief and chief executive.
The War Powers resolution requires the president to inform Congress of military action.
