The complete findings of special counsel Robert S. Mueller III’s investigation into Russian interference in the 2016 elections may not become public when the probe is completed, California Rep. Adam B. Schiff, the top Democrat on the House Intelligence Committee, said Friday.

“One of the issues I have raised with the deputy attorney general” Rod Rosenstein is “how are we going to deal with this when the investigations come to an end?” Schiff said, referring to findings of the Mueller probe. “Will there be a report to Congress and what will Bob Mueller be able to disclose publicly?”

Schiff’s comments came at an event hosted by the Council on Foreign Relations in Washington.

“These are still very open questions,” Schiff said. “I have to think and I have to hope that the public need to know is so profound that what Mueller finds will be shared with Congress and Congress will be empowered to share it with the country.”

Schiff said Rosenstein’s memo last May that laid out reasons why then-FBI Director James B. Comey should be fired included Comey’s public airing of details of the investigation into Hillary Clinton’s email server use. President Donald Trump subsequently cited the Rosenstein memo as the reason for firing Comey. It is unclear if the Justice Department would take the same position when it comes to making public whatever Mueller finds.
