The court on Thursday prevented the administration from asking a question about the 2020 census, which is asking for citizenship for the time being. Critics argued in court that the issue was an attempt to intimidate non-citizens and Hispanic households and would lead to a decline in return rates and an under-representation of minorities, who generally vote democratically.
"Can anyone really believe that as a big country we are not able to ask whether someone is a citizen or not," wrote Trump. "Only in America!"
On Capitol Hill, Democratic committees convened a coordination call late Thursday afternoon after Trump weighed the census for the first time.

Administration had previously told the court that the questionnaire should be printed by the end of June and could not be delayed.
