JD Vance says DOJ looking into if Ilhan Omar committed immigration fraud amid brother-marriage allegations

"You read the things about Ilhan Omar… who she married and whether she didn't marry this person or that person," Vance said. "It certainly seems like something fishy is there, but everybody's entitled to equal justice under the law."

The comments follow a podcast interview in March, during which Vance told conservative commentator Benny Johnson that he had spoken with White House immigration advisor Stephen Miller about potential legal action against the congresswoman.

"We think Ilhan Omar definitely committed immigration fraud against the United States of America," Vance said at the time.

Omar has long been dogged by allegations that she married a man critics allege is her brother, as part of an immigration scheme. Omar has denied the allegation, and the claim has not been proven in public records. In December, she dismissed the claims as "bigoted lies," writing on social media that Trump was obsessed with her.

"He needs serious help," Omar wrote on X. "Since he has no economic policies to tout, he's resorting to regurgitating bigoted lies instead."

Omar, who was born in Somalia, arrived in the U.S. in 1995 after her family was granted asylum. She became a naturalized U.S. citizen in 2000.

According to reports, Omar entered a religious marriage with Ahmed Abdisalan Hirsi in 2002. In 2009, she legally married Ahmed Elmi, a British citizen, whom some allege is her brother. Despite the legal marriage to Elmi, Omar reportedly maintained her religious union with Hirsi, with whom she continued to have children.

On Tuesday, Vance reiterated that authorities would investigate the matter.

"If we think that there's a crime, we're going to prosecute that crime," he said. "And that's something the Department of Justice is looking at right now."
