BALDWIN: Just in to CNN, new evidence has been submitted in one of the biggest cases being decided by the U.S. Supreme Court, whether the Trump administration can add a citizenship question to the 2020 census. Challengers to the White House, including the ACLU, say they have proof the move was politically motivated. CNN Supreme Court reporter Ariane de Vogue is with me with more. And so, Ariane, what is the ACLU submitting here?</s>ARIANE DE VOGUE, CNN SUPREME COURT REPORTER: Right. Well, the challengers to the administration's decision, they said in this filing that they have new evidence that that decision was politically motivated. They obtained a new trove of documents from an individual who they say played a significant role in the administration's decision. That man's name is Dr. Thomas Hofeller. He has since died. But in 2015, he wrote a study on the issue. And he said that such citizenship data would be -- quote -- "advantageous to Republicans and non-Hispanic whites." And the reason this is important is that the administration has said all along that the decision was made to better comply with the Voting Rights Act. They have always pushed back hard that it was politically motivated. And this could be the first concrete evidence to the contrary. Remember, every lower court that heard this case ruled against the administration. But the Supreme Court heard arguments in April. They're considering it. But, during oral arguments, it seemed like the conservatives were ready to side with the government. A Department of Justice official said on background today that they did not know about these documents. They're looking into it right now, and that they will respond in court. So that's where it is, this new evidence, Brooke.</s>BALDWIN: Ariane, thank you very much. Let me get to this breaking news to us here at CNN regarding the border. President Trump is considering a new rule.
