Ross has so far avoided a court-ordered deposition about his decisions; Democrats in the House have indicated they would still like to question Ross about how the citizenship question was dealt with.
"Putting a citizenship question on the census is a cynical and sinister attempt to suppress participation and undercount immigrants short changing fair apportionment of resources and political representation," said Sen. Cory Booker (D-NJ).
The issue of counting everyone - illegal immigrants included - is a sensitive political matter, because the census determines not only the apportionment of Congress, but also the level of aid which can come from the federal government for a variety of federal programs.
"It is important to conduct a census which is comprehensive and accurate," said Rep. Albio Sires (D-NY).
"This citizenship question brings together @realDonaldTrump’s anti-immigrant agenda and his attempts to undermine representative democracy and has no business in the #2020Census," tweeted Sen. Jeff Merkley (D-OR).
