U.S. Rep. Al Green, a Texas Democrat, did his best to make “good trouble” during President Donald Trump’s first address to Congress since taking office in January.

Brandishing his cane, the Lone Star septuagenarian rose from his seat in the U.S. House chamber and challenged Trump’s claim that he has a sweeping mandate to enact the tidal wave of changes his Republican administration has unleashed within the federal government.

Green stood alone, with his Democratic colleagues content to sit silent and hold quaint church fan signs with words that called the president a liar and criticized billionaire bureaucrat Elon Musk.
