Washington (CNN) -- As President Barack Obama decides whether to strike ISIS inside Syria, he has political considerations as well. U.S. lawmakers are watching critically as Obama weighs options on how to deal with the threat from ISIS, the Islamic State in Iraq and Syria. Many have argued the surge of ISIS is the direct result of lack of strategic action to date from Obama, while others are questioning how broadly Obama's executive authority extends when it comes to taking militarily action. Rep. Adam Schiff, the top Democrat on the House Intelligence Committee, tells CNN that unless the United States or its citizens face an imminent threat from ISIS, Obama must seek approval from Congress before extended airstrikes against ISIS inside Syria.
