Democrats pressed Commerce Secretary Wilbur Ross Thursday on his decision to add a citizenship question to the federal census, alleging that prior testimony by Ross was disproven by newly-discovered information.

“We gave very serious questions about whether Secretary Ross was truthful when he appeared before Congress last year and testified on there occasions that he added the citizenship question on because the Department of Justice requested it,” said Oversight and Reform Committee Chairman Elijah Cummings, D-Md.
