All 4 Democratic congresswomen of 'The Squad' are heading back to Congress — and with backup

• "The Squad" — Reps. Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan — secured their seats in the House of Representatives in Tuesday's election.
• The four women of color lawmakers were elected in the 2018 midterm elections.
• In their first term, members of the Squad openly criticized President Trump and his administration's policies including those around immigration, climate change, and racial justice.
• The Squad is expected to expand with the election of several progressives and anti-establishment Democrats to Congress.

All four members of "the Squad" — Reps. Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan — won their re-election bids to the House of Representatives on Tuesday, cementing their progressive flank in the Democratic Party for another two years.

Omar won against Republican Lacy Johnson to represent the state's 5th District. Ocasio-Cortez, who was the overwhelming favorite in her reelection race in New York's 14th Congressional district, beat out GOP opponent, John Cummings, who raised about $10 million. While Pressley defeated independent Roy Owens in Massachusett's 7th District and Tlaib surpassed Republican David Dudenhoefer for Michigan's 13th Congressional District.

Notorious for their solidarity, sisterhood, and friendship, "The Squad" name first started as a 2018 photo caption on Instagram and eventually evolved, according to ABC News. The four women of color lawmakers saw historic wins in 2018 and quickly became prominent figures as they rallied for marginalized communities while drawing the ire of the GOP and President Donald Trump for their progressive views.

Trump and the Squad clashed over several issues, including immigration and climate justice, but most notably after racist tweets sent from the president last July, telling the four women to "go back" to the "broken and crime infested places from which they came."

As Business Insider's Eliza Relman reported, at the time a racially-charged rift had also emerged between the Squad and Democratic establishment, laying bare tensions between the party's progressive caucus and congressional leadership.

But the "resilient" Squad is expected to grow in numbers. On Tuesday, the group of lawmakers added newly-elected members, including Cori Bush and Jamaal Bowman.

Bush, a Black Lives Matter activist won her bid for a House seat in Missouri's 1st Congressional District, becoming the first Black woman to represent the state in Congress.

In October, she tweeted the squad was "about to be a lot more than" just "AOC plus 3," as Trump has dubbed the group.

"Our progressive movement is here to stay, and we're only getting stronger," Bush wrote on Twitter.

Bowman, who ran on an anti-establishment message, defeated a long-term incumbent to win a House seat representing New York's 16th Congressional District.

"it's time for a new era," he tweeted Tuesday.

Here are the four women that new Squad members will be joining on Capitol Hill in the 117th Congress.
