The house oversight committee has voted to hold Attorney General William Barr and Commerce Secretary Wilbur Ross in contempt for failing to produce documents related to a citizenship question on the 2020 Census.
It comes after the White House invoked executive privilege to prevent lawmakers from gaining access to the documents.
The House Oversight Committee had subpoenaed Barr and Ross to obtain those documents.
They wanted to understand exactly why the administration opted to add the question, which some say may stop migrants from responding.
But the White House moved to block that in an effort to avoid a precedent in which congress could demand information on every administration decision.
President Trump continues to defend the census question.
Recently, the supreme court took a case on the question after a lower court ruled it was unlawful.
The justices are expected to have their own decision on that by the end of the month.
