(WASHINGTON) -- A Democratic senator says Homeland Security Secretary Kristi Noem provided false testimony to the Senate Judiciary Committee.
In her appearance before the committee on Tuesday, Noem was asked by Sen. Richard Blumenthal, D-Conn., whether her adviser Corey Lewandowski, who is serving as a special government employee, has any role in approving DHS contracts, and she said no.
"Evidence suggests that your testimony was false. Internal DHS records show that Mr. Lewandowski has personally approved contracts at DHS, including, but not limited to, a multimillion-dollar contract," according to a letter Blumenthal sent to Noem on Wednesday. "And current and former DHS employees have stated that Mr. Lewandowski's signature is a green light for money to be transmitted to contractors."
Blumenthal sent the letter on Wednesday night, after Noem’s testimony in front the House Committee.
In a follow-up appearance before a House committee on Wednesday, Rep. Jared Moskowitz asked Noem if she would like to correct her answer from Tuesday.
"What I would say is that he is an adviser to the Department of Homeland Security," she said.
Sources have told ABC News that Lewandowski is Noem's de facto chief of staff, despite having a 130-day cap on being able to work at the department, due to his status as a special government employee.
According to multiple sources, Lewandowski and Noem both approve contracts and "nothing" gets to the secretary without Lewandowski's approval.
Oftentimes, Lewandowski travels with the secretary to her public events, and on multiple occasions ABC News has seen Lewandowski behind the scenes at events the secretary is speaking at.
When asked by two Democratic representatives if the two were romantically linked, Noem did not deny it and instead called the two Democratic members' line of questioning "garbage."
Lewandowski and Noem have both previously denied any romantic relationship. Both are married to other people.
The department didn’t immediately respond to the letter, or about Lewandowski’s role at DHS.
