When Donald Trump gives his first State of the Union address, it turns out that he won't have all of the members of Congress — or even the Supreme Court —present. So far, thirteen Democratic congresspeople and one justice have announced that they have chosen not to attend. People who are boycotting the State of the Union all have their own specific reasons for doing so, but the overarching theme of their protests is that they feel that they cannot support various statements that the president has made or policies that he's supported. Some simply made other plans.
This isn't the first time that Democratic congresspeople have boycotted a major Trump event; dozens of Democratic members of the House chose not to attend Trump's inauguration, particularly after Trump made a disparaging remark towards civil rights leader and congressman John Lewis. This time, while fewer members of the House will be skipping the event, several of them have cited Trump's disparaging and vulgar comment about "shithole countries" as a reason why they will not be in attendance.
Members of Congress are free to attend or not attend as they see fit, but the decisions to boycott have drawn criticism as being overly divisive. The congresspeople in question, however, evidently see their presence as a measure of support too strong for them to express. Here are the Congress members who have chosen to boycott the State of the Union.
