The House Oversight and Reform Committee plans to vote next week on holding Attorney General William Barr and Commerce Secretary Wilbur Ross in contempt after they missed a subpoena deadline to produce documents the panel was seeking as it investigates why a question about citizenship was added to the 2020 census, Chairman Elijah E. Cummings said Friday.

The Maryland Democrat, in a statement, called the two departments’ reasons for not producing documents by Thursday “case studies in double-speak,” and said the administration has consistently resisted the panel’s probe into the addition of the question to next year’s census.

Cummings argued that “rather than cooperate, they have decided that they would rather be held in contempt of Congress.”

Administration officials have slow-walked the investigation for months, Cummings argued, producing documents and witnesses only under threat of subpoena. He noted Ross refused to testify at all.
