Donald Trump struck a triumphant tone in Tuesday's State of the Union address, staking his bid for re-election squarely on the U.S. economy and embracing the deep partisan rancor over his presidency on the eve of his likely acquittal in the Senate's impeachment trial.

As he took to the dais, Trump turned his back on House Speaker Nancy Pelosi as she offered to shake his hand. When he concluded his remarks, Pelosi could be seen directly behind the president, ripping up a printed transcript of his speech.

The core of Trump's remarks, though, was U.S. economic growth — the pillar of his campaign for re-election in 2020 and what he called "the great American comeback."
