DNC chairman Tom Perez equated the question regarding citizenship on the U.S. Census to voter suppression during an MSNBC interview on Tuesday.

Democrats have been opposed to plans by the Trump administration to reinsert a question as to whether or not the respondent was a United States citizen.

"They want to change it to count the number of U.S. citizens so that they can engage in very not subtle voter suppression," Perez said. "That is illegal and that is totally inconsistent with what the North Star of the census in Republican and Democratic administrations have been."
