President Obama will enter the Congressional Chamber and begin his State of the Union speech at 9 pm EST. If his past is any indicator, he will roughly end his speech an hour or so after the 9 o'clock start time. Marco Rubio will then make the Republican response. So expect all the political back and forth to end around 10:30 pm EST.
