Commerce Secretary Wilbur Ross has proven himself to be one of President Trump’s greatest allies in the quest for economic nationalism with his defiance of the Washington, D.C., political establishment in deciding to add the citizenship question to the 2020 Census.

Ross’s Commerce Department announced this week that he would mandate that the 2020 Census ask respondents whether or not they are American citizens in order to gather more accurate data on the U.S. population and to better enforce the Voting Rights Act.
