Congresswoman Ilhan Omar (D-Minn.) is officially under investigation by the Federal Bureau of Investigation for possibly marrying her own brother, according to the New York Post.

Two FBI agents went to Minnesota in October to interview someone with knowledge of the situation, who handed over numerous documents that could prove the case against Omar. The claims maintain that Omar’s first husband, Ahmed Nur Said Elmi, is her own brother, and that she only married him so that he could get a green card to come to America.

If the allegations are true, then Omar would be guilty of marriage fraud, which is punishable by up to five years in prison and a fine of $250,000.

Her possible marriage to her brother is just one of the many controversies involving the Muslim Congresswoman, who has become one of the most unpopular political figures in the country. Omar has made numerous anti-Semitic, anti-white, and anti-American statements, and also drew fury for describing 9/11 as “some people did something.”

She also recently divorced her second husband and father of her three children, Ahmed Hirsi, due to an affair she was having with political consultant Tim Mynett. Mynett, who has been paid heavily by Omar’s campaign since her first congressional run in 2018, is also married, but left his wife and child to be with the 38-year-old Omar.
