Rep. Ilhan Omar, a Democrat from Minnesota, a Muslim and a newcomer to Congress, already is causing controversy, with a series of anti-Semitic comments, her defense of al-Qaida, her explosions at reporters and her alignment with an extreme left faction in the Democratic Party.

She's already the target of a petition demanding her resignation.

Now, the Department of Homeland Security is being urged to investigate her and begin deportation or other removal proceedings.

The petition was submitted to DHS by former Justice Department prosecutor Larry Klayman, who this week added a demand that the House of Representatives "investigate, consider and take remedial action" on the issue.

The latest controversy was explained by Siraj Hashmi in a commentary in the Washington Examiner.

Hashmi said the Democrats face "a political crisis" with a handful of new lawmakers having drawn "the ire from both sides about their position on the U.S.'s relationship with Israel."

Omar, along with fellow Muslim Rep. Rashida Tlaib, D-Mich., were criticized for "remarks about Israel that were rooted in anti-Semitism."

Before entering Congress, Omar tweeted, "Israel has hypnotized the world, may Allah awaken the people and help them see the evil doings of Israel."

Tlaib and Omar have accused Jewish Americans of dual loyalties. Omar complained in a tweet last month that a Jewish organization that supports Israel influences U.S. elections. "It's all about the Benjamins baby," she wrote, even though the organization she targeted doesn't donate to political campaigns.

Facing backlash, the House Democrats proposed a simple resolution condemning anti-Semitism, but it was delayed due to deep divisions within the party. It later was adopted, without any significant reference to Omar's behavior.

Klayman, who founded Judicial Watch and now runs FreedomWatch, said Omar's "repeated anti-Semitic proclamations are not 'slips of the tongue.'"

"Indoctrinated in radical jihad since a child, Omar's U.S. presence and election are part of jihadi infiltration tactics," he said.

"Muslims who are legitimately American citizens or permanent residents have constitutional rights and these rights must be respected so long as they obey the law and do not seek to undermine our country. If Muslims are elected to Congress or other government positions, this also must be respected under our democratic traditions, so long as they do not violate our laws and do not have terrorist connections, such as Omar!

"However, Omar is not one of these law-abiding and decent Muslims: she is a hateful, dishonest and terrorist-connected threat and scourge on not just Congress but the nation as a whole. Those who support her, including those on the Jewish Left who run interference for her, must also be held to legally account! She must be removed from the House, prosecuted and/or deported."

He cited accusations of immigration marriage fraud against her as well as "her links to terrorist connected groups."

His complaint to DHS was forwarded this week to House Speaker Nancy Pelosi, D-Calif., and various committees.

"Rep. Ilhan Omar, according to extensive reporting by investigative journalists, married her own brother in a sham marriage constituting immigration fraud (while still with her first husband). The basis of Omar's citizenship remains murky, yet her own U.S. citizenship could also prove to be invalid. The sham marriage certainly invalidates her brother's citizenship and Omar could be prosecuted. Conviction of a crime – or ties to terrorist organizations – could also cause Omar to lose her naturalized citizenship," Klayman's statement said.

NBC News reported the current effort in Congress "began as a fresh effort to condemn anti-Semitism in the wake of Rep. Ilhan Omar's latest controversial comments." But it expanded into a vast argument "exposing deep fault lines" among Democrats.

The earlier petition urging Omar's resignation was launched by Laurie Cardoza-Moore, the president of Proclaiming Justice to the Nations.

It cites the "shameful anti-Semitic messaging" from Omar.

It also mentions her links to the Council on American-Islamic Relations, which "was listed as an unindicted co-conspirator in the largest terrorist fundraising operation in the history of the U.S." Omar also helped raise funds for Islamic Relief USA, which has been linked to the financing of terrorism.

Klayman's petition to DHS cited suspicion of marriage fraud, questions about her citizenship since she reportedly came to the U.S. from Kenya, which would mean she was "not eligible to be admitted into the United States as a refugee," and other "removable" offenses.

The DHS was asked to accept evidence in Omar's case, require sworn testimony, search records and investigate "the highly suspect, evasive, ambiguous, apparently false and non-responsive statements and fraudulent alibis of Ilhan Omar."
