Back in 2009, appearing before a joint session of Congress, President Barack Obama was outlining his plans for health care reform when one member of the audience, Republican House member Joe Wilson, shouted out, “You lie!” That wasn’t a State of the Union Address (Obama had given that earlier in the year) – and technically, neither is tonight’s Joint Session address by President Donald Trump. But eight years later, President Trump is in the same hall, addressing the same august body, dealing with the same political divisions and passions.
