Susan Rice Trying To Convince Congress US Must Respond To Suspected Chemical Attack in Syria

Many on Capitol Hill not convinced

(Reuters)—Susan Rice is facing her first key test as President Barack Obama's national security adviser as she helps lead a White House effort to convince a skeptical Congress that the United States must respond to Syria's apparent use of chemical weapons.

Rice has made an abrupt transition from a high-profile and sometimes combative U.S. ambassador, who scolded the U.N. Security Council for failing to agree on Syria sanctions, to a behind-the-scenes power player at the White House.
