Text, timing of Obama AUMF request for Islamic State still in works: source

The final text of President Barack Obama's request to Congress for new authority to use force against Islamic State fighters is still in the works as talks with lawmakers continue, a source familiar with the White House's outreach said on Tuesday. The United States is leading an international coalition fighting Islamic State militants in Iraq and Syria, but Obama has said he would ask Congress for a formal Authorization to Use Military Force (AUMF) for the fight.
