President Donald Trump says he is “very seriously” considering an executive order to get a citizenship question on the 2020 Census.

The Justice Department says it will continue to search for legal grounds to force the inclusion of the question.

Trump says his administration is exploring a number of legal options, but the Justice Department has not said exactly what options remain now that the Supreme Court has barred the question, at least temporarily.

The government has already begun the process of printing the census questionnaire without that question.

The administration’s focus on asking broadly about citizenship for the first time since 1950 reflects the enormous political stakes and potential costs in the once-a-decade population count. The Justice Department says it will continue to look for legal grounds to force the inclusion of a citizenship question on the 2020 Census.

But the department says it’s unclear how that will happen.

That’s according to a lawyer for the plaintiffs who took part in a conference call Friday with government lawyers and a federal judge who demanded clarification of the administration’s plans. President Donald Trump had reopened what appeared to be a final decision by his administration to proceed without the citizenship question on the next census.
