Rep. James Comera 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 large jump in value between 2023 and 2024, according to financial disclosures filed by the congressman.

Comer’s request marks an unusual move by the chairman of a committee that has a history of conducting politically charged investigations, but has almost always targeted government officials outside of Congress. The House Ethics Committee, which is made up of equal numbers of Democrats and Republicans and tries to stay out of political fights, usually handles allegations involving lawmakers and their family members.

Even since her 2018 election as one of the first Muslim women in the House, Omar has received an almost incessant attack from the right. He dismissed allegations of his finances as “misleading” and based on conspiracy theories.

A spokeswoman for Omar, Jackie Rogers, said in a statement that Comer’s letter was “a political stunt” and part of a campaign “intended to raise funds, not actually govern.”

“This is an attempt to orchestrate a smear campaign against the congressman, and it’s disgusting that our tax dollars are being used to discredit him,” Rogers added.

Comer has also shown a willingness to push the traditional parameters of the Oversight panel. In a separate investigation of Jeffrey Epstein, he enforcement of subpoenas for depositions from former Secretary of State Hillary Clinton and former President Bill Clinton, marking the first time a former president has been forced to appear before Congress.

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

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

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

The probe into Omar’s finances stems from a required financial disclosure statement he filed in May last year. She then reported that two companies tied to her husband, a winery called eStCru and an investment company called Rose Lake Capital, have increased in value by at least $5.9 million dollars. Lawmakers report assets in dollar amounts, so it’s unclear how much the companies’ value has increased or what Mynett’s ownership stake is.

Omar also pointed out that her husband’s reported income from the winery was between $5,000 and $15,000 and nothing from Rose Lake Capital.
