Congresswoman Karen Bass, projected to win a fifth term in Tuesday's U.S. midterm elections, has visited Kenya twice in recent years. Following her win in 2016, Omar said her political involvement had become more than "about me or the win or the loss".
Tlaib will fill the seat formerly occupied by Michigan Democratic Rep. John Conyers, who left office past year amid accusations of sexual misconduct.
She also recognized Michigan's Rashida Tlaib who is also Muslim for winning.
Sending her best wishes to Tlaib on the shared historic achievement, Omar wrote on Twitter: "Congratulations to my sister @RashidaTlaib on your victory!"
Omar will take the seat vacated by Minnesota Rep. Keith Ellison, the first Muslim elected to Congress. Ellison is leaving Congress as he vies to become Minnesota attorney general. After fleeing the country's civil war, she spent four years in a refugee camp before coming to the US when she was 14.
The 42-year-old was born in Detroit to Palestinian immigrant parents.
