Judicial Watch, a conservative activist group, filed an ethics complaint against Representative Ilhan Omar for accusations that she married her brother to commit immigration fraud, among other crimes.

A new report, following a three year investigation, alleged that Omar married her biological brother, Ahmed Nur Said Elmi, in 2009 to benefit in some fraudulent way from the marriage.

Omar is a Somali-Ameriacan immigrant who fled Africa for the U.S. with her family when she was a young girl. She became a naturalized U.S. citizen when she was 17. The report alleges that her second husband, Elmi – who she supposedly married when she was still married to her first husband – is actually her brother.

Following the report, and Donald Trump's mentioned of the unsubstantiated evidence, Judicial Watch filed a complaint calling for the House Office of Congressional Ethics to launch a full investigation into the congresswoman's crimes.

'The evidence is overwhelming Rep. Omar may have violated the law and House rules,' Judicial Watch President Tom Fitton wrote in a letter. 'The House of Representatives must urgently investigate and resolve the serious allegations of wrongdoing by Rep. Omar'

'The evidence is overwhelming Rep. Omar may have violated the law and House rules,' Judicial Watch President Tom Fitton wrote in a letter to Office of Congressional Ethics Chairman David Skaggs.

'The House of Representatives must urgently investigate and resolve the serious allegations of wrongdoing by Rep. Omar,' Fitton continued. 'We encourage Americans to share their views on Rep. Omar's apparent misconduct with their congressmen.'

Judicial Watch, which files Freedom of Information Act lawsuits to investigate claimed misconduct by government officials, is requesting the congressional oversight group look at all the alleged crimes outlined in an in-depth investigative report from reporters David Steinberg, Preya Samsundar and Scott Johnson on Powerline blog.

Among the crimes are immigration fraud, which the report claims Omar participated in when marrying Elmi in order for him to obtain U.S. citizenship and emigrate to America from the U.K. – where he is a longtime citizen.

The fraud scheme includes another level in that it aided Elmi to obtain federal student loans in attending North Dakota State University, which he would not have been able to obtain if he weren't a citizen through marriage.

Omar and Elmi divorced in 2017, and as part of the divoce, the report revealed that Omar submitted an 'Application for an Order for Service by Alternative Means' in Minnesota.

Omar married Elmi in 2009, before she had divorced her first husband. The report reveals that Elmi is actually her biological brother. The two divorced in 2017, but Omar claimed she had not seen him since June 2011

Photo evidence, however, suggests Omar may have perjured herself by signing a document claiming she had not seen Elmi. Instagram evidence shows them in an image together in 2015

In the document, the now-Minnesota representative claimed she had not had contact with Elmi after June 2011 and did not know where to find him.

By signing the document, Omar was swearing to the state that 'under penalty of perjury that everything I have stated in this document is true and correct.'

However, Steinberg, Samsunder and Johnson's investigation revealed, with Instagram photo evidence, that Omar and Elmi had met up in London in 2015.

'The facts describe perhaps the most extensive spree of illegal misconduct committed by a House member in American history,' Steineberg alleged.

Judicial Watch claims it is a 'non-partisan educational foundation.'

While speaking with reporters last week, Trump briefly talked about the report on Omar, which brought more attention to the alleged crimes and the fact the progressive representative likely married her brother.

'There's a lot of talk about the fact that she was married to her brother. I know nothing about it,' Trump said before departing the White House last Wednesday. 'I'm sure that somebody would be looking at that.'

The issued garnered more momentum after Donald Trump made mention of the issue during a White House departure last week, saying 'I know nothing about it... I'm sure that somebody would be looking at that'

Last Sunday Trump told the group of lawmakers they should 'go back' to their countries of origin and fix the issues there instead of getting involved in U.S. government

Trump has been at odds with Omar and the rest of the self-described 'squad' of minority freshmen congresswomen.

On July 14, Trump told Omar, Alexandria Ocasio-Cortez, Rashida Tlaib and Ayanna Pressley to 'go back' and fix their countries of origin before wading into U.S. government.

The comments were widely viewed as 'racist,' but the president continued to repeat similar sentiments – like telling people if they don't like America, they can leave, and claiming the four congresswomen are 'not capable' of loving the U.S.

The lawmakers – who were all elected to the House in the 2018 midterm elections – held a press conference last Monday to condemn Trump's words and call for his impeachment.

Of the four in 'the squad,' only Omar was born outside of the U.S.

Ocasio-Cortez is of Puerto Rican descent, Tlaib's parents are Palestinian immigrants and Pressley is African American.
