Ilhan Omar

"We can't allow him to remain in office, it's a matter of preserving our Republic and we need to fulfill our oath," wrote the Minnesota Democrat, as Trump supporters stormed the U.S. Capitol.

Omar, a progressive from Minnesota, made history in 2018 as the first Somali American elected to Congress and is projected to win her Democratic primary.

The first-term progressive has a well-funded challenger. Also Tuesday there are two runoffs in Georgia with controversial conservative candidates.
