Sen. Mark Warner, the vice chairman of the Senate intelligence committee, said Tuesday that the Treasury Department has not fully complied with his committee’s requests for documents relevant to its probe into Russian meddling in the US election.

Likewise, Democrats on the House Financial Services Committee sent a letter on Tuesday to Treasury Secretary Steven Mnuchin requesting records of Trump businesses and any connections to Russia by June 2.

Warner and Senate intelligence committee Chairman Richard Burr, R-North Carolina, sent a request for documents last month to the department’s division on terrorism and financial intelligence.

Warner was addressing the nomination of Sigal Mandelker, the Trump administration’s nominee to run that division at the Treasury Department. He said his support had an “important condition.”

“While the committee has received some documents from Treasury, the information received thus far is insufficient and we’ve expressed this concern to Treasury,” the Virginia Democrat said during a Senate banking committee hearing considering nominations. “I find myself in an undesirable position today, one that could have been avoided by an administration that has blamed Democrats for obstructing their nominees.”

CNN reached out to the Treasury Department for comment and has not yet received a response.

“The truth is, while Chairman Burr and I asked this administration for documentation that we believe necessary to support the Senate Intelligence Committee investigation into Russian interference, unfortunately, the administration so far has failed to make an appropriate appreciation for our sense of urgency by not fully responding to our requests,” the Virginia Democrat said.

“My hope is before Ms. Mandelker comes to the Senate floor, they will respond,” Warner said about a full Senate vote on the nominee and the related material that’s been requested.
