For the second year in a row, Democratic women lawmakers — including House Speaker Nancy Pelosi — wore white Tuesday night to President Trump’s State of the Union address.

The effort was organized by the Democratic Women’s Caucus as a nod to the suffrage movement of the early 20th century that culminated with the ratification of the 19th amendment, granting women the right to vote.

“Proud to join my fellow @HouseDemWomen today as we #WearWhite to show support for the ongoing fight to achieve equality for women across the country,” Pelosi tweeted earlier Tuesday.

Pelosi included a photo showing white-clad Democratic congresswomen standing hand-in-hand on a staircase.

The co-chair of the Democratic Women’s Caucus, Rep. Brenda Lawrence, of Michigan, tweeted that she was donning white Tuesday “because women have been at the forefront of the fight for equal pay, affordable health care, repro freedom & safety from violence and discrimination.”

At last year’s State of the Union address, Democratic women wore white, in part, to honor those who came out to vote in the midterm elections that gave Democrats the House majority.
