While Washington continues to seek a political resolution to the various wars tearing through Syria, it won’t insist on Syrian President Bashar al- Assad’s ouster, Trump’s homeland and counterterrorism adviser Tom Bossert said Thursday. “I don’t think it’s important for us to say Assad must go first,” Bossert said at a security conference. “The U.S. would still like to see Assad go at some point. That would be our desired outcome.”
