Feds deny 'dumpster diving,' but reportedly confirm they have Ilhan Omar's DNA, talked to her sister

Congresswoman Ilhan Omar.

New details about the investigation into U.S. Representative Ilhan Omar of Minnesota have emerged, with federal authorities confirming that they are in possession of the congresswoman's DNA sample, but denying that a method known as "dumpster diving" was used to obtain it. Officials also say they've spoke with Omar's sister in the days since last week's raid of the congresswoman's D.C. home.

According to multiple reports from Fox News, federal authorities have obtained a sample of Omar's DNA, although according to Bill Melugin of Fox News, the sample was not obtained from trash, as previous reports had indicated. Anonymous sources told Melugin reports of "dumpster diving" were "incorrect," but the DHS and DOJ have so far continued to give any on-the-record statements about the state of the investigations

Authorities have also seized Omar's personal passport, though not her official government passport. They believe she has not fled the country, and anticipate that she won't flee due to the optics of such a move, sources told Melugin. 

Meanwhile, Fox News reported, investigators have questioned Sahra Noor, Omar's older sister. According to the sources cited by Fox News, Noor spoke with investigators voluntarily in the days following the raid on Omar's home. The New York Times previously reported that investigators used text messages between Omar and Noor obtained earlier this year as evidence to convince a federal judge to sign a warrant allowing the search of Omar's D.C. home. Noor is among several of Omar's relatives who have been issued federal subpoenas in recent days. 

According to multiple reports over the last week, investigators are working to build a case showing Omar committed immigration fraud, possibly lied about her age to do so, with the goal of denaturalizing and ultimately deporting the congressman who hails from Somalia and came to the U.S. as a teen in the mid-1990s. 

All of this comes amid reports that the now-defunct winery run by Omar and her husband, Tim Mynett, was selling empty barrels to investors. For more on the probe into Omar, watch the video below.
