WASHINGTON (Reuters) - The U.S. Justice Department is still considering how to proceed on an effort to add a citizenship question to the 2020 U.S. Census, according to court papers filed on Friday.

In a filing made in Maryland federal court in response to a court deadline, lawyers for the Trump administration indicated that they have not yet finalized a new rationale for adding the query after being blocked in the Supreme Court on June 27.
