Ilhan Omar, whose victory in a Minneapolis DFL primary last week virtually assured her of becoming the nation’s first Somali-American legislator, denied recent reports that she married her brother to commit immigration fraud while remaining married to the man who is the father of her three children.

“Allegations that she married her brother and is legally married to two people are categorically ridiculous and false,” campaign spokesman Ben Goldfarb said Monday.

The questions surfaced over the weekend in a report on the conservative website Power Line, which gained recognition for its role in covering forged documents relating to President George W. Bush’s service in the Texas Air National Guard. Power Line reported that Omar was married to two men at the same time, including to her brother. The story quickly spread to other conservative-leaning websites and news organizations.

Omar defeated two tough DFL opponents — including the longest serving House member in state history — by marshaling an effective grass roots campaign that surpassed turnout expectations for both white and minority voters.

Omar spent part of her childhood in a refugee camp in Kenya before immigrating to the United States as a child knowing little English.

Hennepin County records show Omar applied for a marriage license in 2002 but never used it. It was not immediately known whom she planned to marry. Seven years later, Omar married Ahmed Nur Said Elmi in Eden Prairie, according to their marriage record. Elmi could not be reached for comment. Minnesota courts have no records of Omar and Elmi filing for divorce. Her campaign flatly denied that Elmi is her brother. It would only say that she and Ahmed Hirsi, who is pictured in campaign literature and is the father of their three children, are together and raising a family. The Star Tribune could not find records in Minnesota showing that the two ever married.
