(CNN) A pair of districts in the Midwest will add Muslim women to the ranks of the US Congress for the first time, CNN has projected.

Michigan Democrat Rashida Tlaib and Ilhan Omar, the Minnesota Democratic-Farmer-Labor Party's nominee, will secure their respective seats in strongly Democratic districts following primary victories earlier this year that effectively decided their races.

Tlaib is endorsed by the Democratic Socialists of America, a burgeoning left-wing group that also counts New York Democratic congressional nominee Alexandria Ocasio-Cortez among its members.

Omar, in addition to being one of the first Muslim women in Congress, will also be the first Somali-American member. She came to the US more than two decades ago as a refugee. Tlaib actually campaigned with Omar ahead of the latter's primary race earlier this year.

Omar also had the backing of Ocasio-Cortez in her primary race, and she will come to Congress having been an open critic of the Israeli government's treatment of Palestinians.
