Trump's first address to Congress - Feb. 28

I wonder if anyone will have the audacity to tell him "You Lie!" when he does.

When is the official state of the union address??

Next year.  New presidents don't have official SOTUs in their first year, but they usually call a joint session anyway.

But of course next year we could have a totally new president, so who knows?

It used to be the case that outgoing presidents would give a final State of the Union message. Ford was the last to do so by a speech and Carter gave a written departing message. Ford's final SotU is also the first I recall watching.
