Assistant Attorney General Joseph Hunt says "there may be a legally available path" under last week's Supreme Court decision that blocked the question, at least temporarily.
Hunt made his comments on a conference call with U.S. District Judge George Hazel Wednesday afternoon, following a tweet from President Donald Trump insisting that efforts to include the citizenship question would proceed.
The Justice Department had insisted to the Supreme Court that it needed the matter resolved by the end of June because it faced a deadline to begin printing census forms and other materials.
