The House will “soon” vote to hold Attorney General William Barr and Commerce Secretary William Ross in contempt of Congress for defying subpoenas for documents explaining the administration’s rationale for wanting to add a citizenship question to the census, Speaker Nancy Pelosi wrote in a “Dear Colleague” letter on Monday.

The Oversight and Reform Committee last month approved a contempt resolution against Barr and Ross that included language to refer the matter to the U.S. attorney in Washington for possible criminal charges, as well as authorize the pursuit of a lawsuit.

The Justice and Commerce departments have provided the Oversight Committee with some documents on the citizenship question while withholding others over claims of executive privilege.

The House, in a floor vote the day before the Oversight contempt markup, already gave all committees the authority to file lawsuits to enforce their subpoenas.

That means a floor vote is not needed for Democrats to try to get a court order forcing Barr and Ross to hand over the outstanding documents they requested.
