Rep. James Comer, R-Ky is going all-in on investigating Hunter Biden’s shady foreign business deals now that Hunter’s accounts have been flagged and reported by U.S. banks.

Comer serves as the ranking member on the House Oversight Committee and wrote a letter to Secretary of the Treasury Janet Yellen on Wednesday demanding details about Hunter’s foreign business dealings while accusing the Biden administration of stonewalling Republicans as they conduct an investigation, according to Fox News.

Rep. Comer reached out to Yellen this past May asking her for the reports by the banks, of which he says went unanswered.

“On May 25, 2022, I wrote to you requesting information regarding Hunter Biden and other Biden associates and family members’ financial transactions flagged by U.S. banks for reporting to the Financial Crimes Enforcement Network (FinCEN) through Suspicious Activity Reports (SARs),” states Comer.

“The Biden Administration is restricting Congress’ access to SARs, and Committee Republicans are investigating whether this change in longstanding policy is motivated by efforts to shield Hunter Biden and potentially President Biden from scrutiny,” Comer continued, noting that the secretary did not comply with a June 8 deadline for information.

The letter continued: “Treasury’s actions call for investigation and raise new questions about the degree to which the Biden Administration is using the federal government to provide cover for the Biden family and its associates … The American people deserve to know whether the President’s connections to his son’s business deals occurred at the expense of the United States’ interests and whether they represent a national security threat.”

As a result, on behalf of the Oversight Committee, Comer sent letters to a handful of U.S and foreign banks in May seeking information on whether the Biden family “sold access” into the top tier of the government to enemies of the United States.

According to an aide for Comer, the committee has not received any responses from the banks, which said they can not comply without a subpoena.

“The Biden Administration is restricting Congress’ access to SARs, and Committee Republicans are investigating whether this change in longstanding policy is motivated by efforts to shield Hunter Biden and potentially President Biden from scrutiny,” Comer continued, noting that the secretary did not comply with a June 8 deadline for information.

The lawmaker set a new deadline of July 20 for the Treasury to turn over the SARs which by law they must hand over.
