President Trump on Thursday said his administration is working “very hard” on Independence Day to try to find a way to include a US citizenship question on the 2020 Census.

“So important for our Country that the very simple and basic ‘Are you a Citizen of the United States?’ question be allowed to be asked in the 2020 Census,” the president said in his first tweet on the holiday.

“Department of Commerce and the Department of Justice are working very hard on this, even on the 4th of July!” he added a few minutes before wishing a happy Fourth.

On Wednesday, the president appeared to cast doubt on his own commerce secretary’s statement that the census would not include a question on citizenship — calling the reports ”FAKE!”

“We are absolutely moving forward, as we must, because of the importance of the answer to this question,” he tweeted.

Commerce Secretary Wilbur Ross on Tuesday said that “the Census Bureau has started the process of printing the decennial questionnaires without the question.”

Critics charge that the controversial question would result in an undercount of Latinos and other minorities.

A Supreme Court ruling last week blocked the question’s inclusion, at least temporarily.

The Justice Department had insisted to the court that it needed the matter resolved by the end of June because of a deadline to begin printing census forms and other materials.

But on Wednesday, Justice officials told a federal judge in Maryland that they believed there could be a way to meet the president’s demands.

“There may be a legally available path,” Assistant Attorney General Joseph Hunt told US District Judge George Hazel during a conference call with parties to one of three census lawsuits.
