WASHINGTON (AP) — Melania Trump on Monday marked the 100th anniversary of women gaining the right to vote with an art exhibit based on works by children from all 50 states and the District  of Columbia.

The first lady called adoption of the 19th Amendment to the Constitution that granted women voting rights a “turning point” in the women’s rights movement.

She unveiled the exhibit on Pennsylvania Avenue outside the White House and said it would encourage to talk to their children about the “important conversations taking place around equality” and help them understand the history behind women’s suffrage.

Mrs. Trump also used her appearance — on the opening day of the Republican National Convention — to promote certain aspects of her husband’s record on women’s issues. Polls show President Donald Trump facing a yawning deficit with female voters.

The first lady said that, under “our administration,” the child tax credit was doubled, women experienced some of the lowest rates of unemployment on record and the Republican president put women in many senior administration positions.

One of those women, White House counselor Kellyanne Conway, one of the president’s longest-serving aides, announced late Sunday that she is leaving at the end of August to spend more time with her four children. Conway was Trump’s third campaign manager and made history in 2016 as the first woman to steer a winning presidential campaign.

Conway was among some of the young artists, female administration officials, Cabinet secretaries and others who joined Mrs. Trump for the launch of the “Building the Movement: America’s Youth Celebrate 100 Years of Women’s Suffrage” exhibit.
