"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."
"This is just another divide-and-conquer effort. This is a first cousin of these voter ID laws sought to make sure that African Americans and Latinos can't vote," he added. "This is not who we are as a nation. This is not why people died for the passage of the Voting Rights Act."
