There may be a few more empty chairs at the State of the Union this year, as several Democrats have announced plans to boycott the event.

Their colleagues, on the other hand, have promised to fill dozens of seats with so-called "Dreamers," illegal immigrants who were brought into the country as children.

Members of the House and Senate are each allowed to bring one guest of his or her choosing. And the list just keeps growing.
