President Trump snubbed House Speaker Nancy Pelosi's handshake as he took the stage at the State of the Union address Tuesday.
The other side: Pelosi snubbed Trump back, introducing him only with the lead: "The President of the United States."
A speaker would have usually used the language: "I have the high privilege and distinct honor of presenting to you the President of the United States."
The big picture: Trump's address comes just weeks after the House voted to impeach him and one day before the Senate is set to vote for his acquittal. Whether he mentions impeachment will be a key note to watch for the night.
