Their names have circulated for months, but most hit the headlines on Election Day 2018.
That's when American voters ushered in a new class of lawmakers who are changing the face of the House of Representatives to become more female and more racially diverse than ever.
Ilhan Omar (D-Minn.)
For Rep. Ilhan Omar, a Democrat who is the first Somali-American in Congress, the history-making began when she touched down at a Washington airport Wednesday night with her father. The airport wasn't new to her family – in fact, they'd been there at a pivotal point in their lives – but Wednesday's reason surely was. Omar made history when she was sworn in becoming the first member of Congress to wear a hijab ending a 181-year ban on any type of headwear on the House floor.
"23 years ago, from a refugee camp in Kenya, my father and I arrived at an airport in Washington DC," Ilhan wrote on Twitter Wednesday night. "Today, we return to that same airport on the eve of my swearing in as the first Somali-American in Congress."
Omar, who represents Minnesota's 5th Congressional District, and fellow Democrat Rep. Rashida Tlaib, who represents Michigan's 13th Congressional District, are the first Muslim women to serve in Congress. The two worked alongside each other when Tlaib campaigned with Omar during her primary.

A recent photo by famed portrait photographer Martin Schoeller has circulated their social media feeds and others, lighting up the internet because of all the firsts in one frame: Reps. Alexandria Ocasio-Cortez, the youngest woman ever elected to Congress at 29; Ayanna Pressley, the first black woman to be elected to Congress from Massachusetts; Omar, Deb Haaland and Sharice Davids, the first two Native American women elected to Congress; and Veronica Escobar, one of the first two Latina women ever elected to Congress from Texas.
Rep. Alexandria Ocasio-Cortez (D-NY)
Rep. Alexandria Ocasio-Cortez is the youngest woman ever elected to Congress at age 29. She defeated former Rep. Joe Crowley, in a June primary. Crowley was the chair of the House Democratic Caucus. This was Ocasio-Cortez’s first campaign for office but prior to her campaign she worked as an organizer for Bernie Sanders’s 2016 presidential campaign.
"They ain't ready," tweeted Omar with the photo. "Si, se puede," Ocasio-Cortez, who goes by just "@AOC" on Twitter, tweeted out to her fierce following.
Rep. Deb Haaland (D- N.M.)
Rep. Deb Haaland made history as one of two Native American women elected to Congress. The daughter of a Marine Corps and Navy veterans, she is an enrolled member of Pueblo of Laguna. Haaland served as President Barack Obama’s Native American vote director during his 2012 re-election campaign. Haaland replaces former Rep. Michelle Lujan Grisham who successfully ran for Governor.
In the 116th Congress, 126 women are serving overall, increasing the percentage of women in Congress from 20 percent to almost 24 percent, according to the Center for American Women in Politics. Forty-three women of color were elected to the House and four were elected to the Senate.
