Kristi Noem has been the subject of long‑running rumors that she had an extramarital affair with Republican operative Corey Lewandowski, but both of them have repeatedly and explicitly denied it, and no conclusive proof has been made public.

Quick Scoop: What’s Being Alleged?

  • Multiple political and media reports describe rumors of a romantic relationship between Kristi Noem and Corey Lewandowski, a longtime Trump ally and operative.
  • These rumors have circulated since at least 2021, when a conservative outlet first published anonymous claims of an affair.
  • More recently, as Secretary of Homeland Security, Noem has faced questions in Congress about her relationship with Lewandowski, who serves as a top adviser to her.

What Noem Says

  • Kristi Noem has repeatedly called the affair allegations “total garbage” and “tabloid” nonsense, stating that she has refuted them for years.
  • She continues to insist that her relationship with Corey Lewandowski is professional, not romantic.

What Reports and Commentators Say

  • Several articles describe the supposed affair as an “open secret” or “worst‑kept secret in D.C.” based on unnamed sources around Trump‑world and the Department of Homeland Security.
  • Some coverage notes that, according to unnamed officials, concerns about the rumored relationship influenced internal decisions about Lewandowski’s official role around Noem.

Forum‑style chatter and TV commentary often treat the rumor as if it were true, but they generally lean on anonymous sources, speculation, and circumstantial details rather than hard evidence.

So, “Who Was She Having an Affair With”?

If you phrase it as “who was Kristi Noem having an affair with,” the name that appears in virtually all reporting and online discussion is Corey Lewandowski.

However:

  • The allegation remains unproven in any formal sense.
  • Both Noem and Lewandowski deny that they had an affair.

A more accurate way to put it is:

Rumors and media reports allege that Kristi Noem had an affair with Corey Lewandowski, but both have strongly denied the claim and no definitive public evidence has confirmed it.

TL;DR: The widely discussed allegation is that Kristi Noem was having an affair with Corey Lewandowski, but it is still an allegation, not an established fact, and both parties say it’s false.
