Standing before a Congress and nation sharply divided by impeachment, U.S. President Donald Trump used his State of the Union address Tuesday to extol a "Great American Comeback" on his watch, three years after he took office decrying a land of "American carnage" under his predecessor.

The first president to run for reelection after being impeached, Trump received a raucous but divided response from Congress with Republicans in the House of Representatives chanting "Four More Years" while Democrats stood mute.
