During Mr. Trump's first address to a joint session of Congress in 2017, Democratic congresswomen wore white to highlight women's rights. Last year, when then-President Joe Biden delivered a State of the Union address, caucus members also wore white to bring attention to reproductive rights.

Dozens of female Democratic lawmakers have arrived in the House chamber clad in pink pantsuits to send a message to Republicans and President Trump.

From all-pink attire to T-shirts imprinted with “RESIST,” Democratic politicians used clothing to symbolize their views, during the president’s address to a joint session of Congress.
