Conservative watchdog group Judicial Watch announced Tuesday that it filed an ethics complaint against Rep. Ilhan Omar over allegations that she married her brother and actively facilitated an immigration fraud scheme. The notice was hand delivered to U.S. House of Representatives Office of Congressional Ethics David Skaggs calling for a full investigation into Omar’s scheme.

“The evidence is overwhelming Rep. Omar may have violated the law and House rules. The House of Representatives must urgently investigate and resolve the serious allegations of wrongdoing by Rep. Omar,” stated Judicial Watch President Tom Fitton. “We encourage Americans to share their views on Rep. Omar’s apparent misconduct with their congressmen.”

The letter to the chairman highlights that there is “substantial” evidence that “Rep. Ilhan Omar may have committed the following crimes in violation of both federal law and Minnesota state law: perjury, immigration fraud, marriage fraud, state and federal tax fraud, and federal student loan fraud.”

Investigative reporters David Steinberg, Preya Samsundar and Scott Johnson verified Omar engaged in immigration fraud by marrying her biological brother and later divorcing him claiming she no longer had contact with him, according to Judicial Watch.

“The evidence developed by Mr. Steinberg and his colleagues demonstrates with a high degree of certainty that Ms. Omar not only had contact with Mr. Elmi, but actually met up with him in London in 2015, which is supported by photographic evidence. Ms. Omar signed the “Application for an Order for Service by Alternate Means” under penalty of perjury. The very document that Ilham Omar signed on August 2, 2017 bears the following notation directly above her signature: “I declare under penalty of perjury that everything I have stated in this document is true and correct. Minn. Stat. § 358.116,” according to the letter.

Omar’s brother, through this process, was able to emigrate to the U.S. from the U.K. and may have also obtained federal student loans to attend school at North Dakota State University.

In addition to alleged immigration fraud, The State of Minnesota earlier found Omar “violated state campaign finance laws for improper use of campaign funds.” Further, in 2014 and 2015, Omar submitted ““joint” tax returns with a man who was not her husband, named Ahmed Hirsi, while she was actually married to Ahmed Elmi.”
