Several current and former law enforcement officials said an Obama-era investigation found some evidence that Ms. Omar had entered into a sham marriage with a man who may have been her brother.
The disclosure brings renewed attention to a marriage that has been the subject of years of public dispute and political attacks. Omar has long denied wrongdoing related to her past marriage and has pushed back against claims about her personal life.
The officials described the earlier inquiry as one that examined immigration-related questions, and said its findings were not the end of the matter. Some of the people who spoke to reporters said the evidence gathered at the time was incomplete, and that the question of what it showed remains contested inside government circles.
The renewed scrutiny arrives at a politically sensitive moment for Omar, a Minnesota Democrat who has been a frequent target of criticism from Republicans. Her supporters have characterized the recurring attention to her marriage as a pattern of harassment, while critics argue that questions about the relationship deserve direct answers.
The New York Times reported that it was not able to independently confirm the full scope of the investigation's findings, and that officials offered differing accounts of how much weight the evidence should carry.
