WASHINGTON (AP) — The chairman of the House Oversight Committee on Friday requested records related to firms partially owned by the husband of Minnesota Democratic Rep. Ilhan Omar, taking the extraordinary step of scrutinizing the spouse of a sitting House member.

Rep. James Comer, a Kentucky Republican, released a letter to Timothy Mynett, a former Democratic political consultant who is married to Omar, requesting records related to a pair of companies that had a substantial jump in value between 2023 and 2024, according to financial disclosures filed by the congresswoman.

Comer’s request marked a highly unusual move by the chair of a committee with a history of taking on politically-charged investigations, but almost always focused on government officials outside of Congress. The House Ethics Committee, which is comprised of an equal number of Democrats and Republicans and tries to stay away from political fights, typically handles allegations involving lawmakers and their family members.

Yet since her 2018 election as one of the first Muslim women in the House, Omar has received nearly-nonstop attacks from the right. She has dismissed allegations around her finances as “misleading” and based on conspiracy theories.

Omar’s office did not immediately respond to a request for comment.

Comer has also displayed a willingness to push the traditional parameters of the Oversight panel. In a separate investigation into Jeffrey Epstein He is enforcing subpoenas for depositions from former Secretary of State Hillary Clinton and former President Bill Clinton, marking the first time a former president will be forced to appear before Congress.

In the letter to Mynett on Friday, Comer said, “There are serious public concerns about how your businesses increased so dramatically in value only a year after reporting very limited assets.”

There is no evidence of wrongdoing by Omar, but President Donald Trump also said last month that the Department of Justice is looking into her finances.

In response to the president, Omar said on social media that “your support is collapsing and you’re panicking,” adding that “Years of ‘investigations’ have found nothing.”

The scrutiny of Omar’s finances comes from a required financial disclosure statement she filed in May last year. She reported then that two firms tied to her husband, a winery called eStCru and an investment firm called Rose Lake Capital, had risen in value by at least $5.9 million dollars. Lawmakers report assets within ranges of dollar figures, so it was not clear exactly how much the firms had risen in value or what ownership stake Mynett had in them.

Omar has also pointed out that her husband’s reported income from the winery was between $5,000 and $15,000 and none from Rose Lake Capital.
