As the U.S. Supreme Court mulls whether U.S. Commerce Secretary Wilbur Ross will be deposed in a lawsuit over his agency’s decision to ask about immigration status on the next census, new questions have emerged on the involvement of former White House Chief Strategist Stephen Bannon.

The U.S. Department of Justice said in a filing this month that Bannon had at least one conversation with Ross early on in the Trump presidency about adding the question, several months before it was formally requested by the DOJ.
