An "imitation census" mailed by the Republican National Committee to addresses in Bozeman, Mont., that also solicits money for President Donald Trump's re-election.

Civil rights groups Thursday blasted the Republican National Committee, claiming the group violated federal law and is trying to sow confusion after it mailed imitation census forms meant to mimic the real decennial to Montana voters to solicit money for President Donald Trump's re-election campaign.

The RNC sent the forms — titled the 2019 Congressional District Census Mailer — to addresses in Bozeman, Montana, and informed recipients that "Your Participation is Urgently Needed," with instructions such as "Do Not Destroy Official Document," and "return your Census Document." Sent in late September, the forms told recipients to return by Oct. 15.
