The House Oversight Committee has voted 24-15 to hold Attorney General William Barr and Commerce Secretary Wilbur Ross in contempt for refusing to turn over subpoenaed materials related to the Census citizenship question.

The big picture: Earlier Wednesday, President Trump asserted executive privilege over the subpoenaed documents on the advice of the Justice Department. The committee is investigating whether the Trump administration’s decision to add a citizenship question to the 2020 Census was politically motivated, a controversy that could have major implications for future federal funding and redistricting.

Ross has defended the citizenship question as necessary to enhance the 1965 Voting Rights Act, despite the Census Bureau’s own analysis that it could scare households with non-citizens into low response rates.
