Constitutional Hurdles Complicate Efforts to Remove Ilhan Omar from Congress

President Trump has publicly called for the resignation of Rep. Ilhan Omar (D-Minn.), citing a Department of Justice investigation into potential immigration fraud and questioning her legal status to serve in Congress. Trump has alleged Omar uses a "fake name" and is a "troublemaker," demanding she "immediately resign from Congress."

The investigation by the Justice Department reportedly involved a raid on Omar's Washington, D.C. home, where federal authorities collected items including phones, notebooks, a camera, and a Somali phrase book. A federal filing in the inquiry lists the congresswoman's name as "Ilhan Nur Said Elmi, a/k/a Ilhan Abdullahi Omar." Omar, when questioned by Fox News, confirmed her name as "Ilhan Abdullahi Omar." Official records from the Clerk of the House of Representatives and the Minnesota state legislature list her as solely "Ilhan Omar" on various financial disclosure reports dating back to 2018.

However, the Constitution grants Congress the ultimate authority over the seating and expulsion of its members. Article I, Section 5 of the Constitution states that each chamber of Congress has the power to judge the elections, returns, and qualifications of its own members. This means that removing Omar from Congress would require action by the House of Representatives itself, not solely by the executive branch or presidential directive.

Republicans aiming to remove Omar face several potential avenues, each with its own challenges. One option is expulsion, which requires a two-thirds vote of the House. This path is considered unlikely given the high threshold and the fact that Omar has not been convicted of a crime. The House has historically expelled very few members; the last instance was former Rep. George Santos (R-N.Y.) in 2023.

Another possibility involves challenging Omar's seating when the new Congress convenes. While the Constitution sets basic qualifications for House members—age 25, citizenship, and residency in the state they represent—the Supreme Court has affirmed Congress's discretion. In the 1968 case Powell v. McCormack, the Court ruled that the House cannot exclude a member-elect who meets these fundamental requirements, even if facing investigation. However, historical precedent, such as the House's delay in swearing in Rep. Frank McCloskey (D-Ind.) in 1985 pending an investigation into his election, suggests that the process of seating new members can be subject to scrutiny and potential delays.

Rep. Morgan Griffith (R-Va.) acknowledged that the House has the "prerogative to seat or not seat and to throw Members out if it so chooses," but emphasized that "there ought to be good sound reasons for it." He compared the threshold for such action to the Supreme Court's famous "I know it when I see it" standard for obscenity.

Legal experts note that the "Speech or Debate Clause" in Article I, Section 6 of the Constitution provides protections for lawmakers regarding their official duties, potentially shielding their communications and documents from executive branch scrutiny, complicating efforts to gather evidence for removal proceedings.

Ultimately, while President Trump and some House Republicans may seek to remove Omar, the constitutional framework provides significant protections for elected officials, making any attempt to expel or unseat her a complex and uncertain undertaking.
