WATCH LIVE: Obama's 2015 State of the Union Address

U.S. President Barack Obama will challenge a skeptical Republican-led Congress on Tuesday to back tax increases on the wealthy to help lift up middle-class  Americans, saying in a State of the Union speech it is time to 'turn the page' from  recession and war. On foreign policy, Obama will call on lawmakers to pass a new authorization of military force against Islamic State militants to replace powers that were given to President George W. Bush to prosecute the Iraq war.
