"We are going to get to the bottom of this," Schiff said. "We are going to share this information with the public. And if the president is serious about all his claims of exoneration, then he should welcome the publication of the report.”

Rep.

Mueller is investigating Russian interference in the 2016 election and possible collusion between the Trump campaign and Moscow. At the conclusion of the special counsel's investigation, Mueller is required to submit a written report to the attorney general.

Attorney General William Barr, who was confirmed earlier this month, did not commit during his confirmation hearing to making Mueller's final report public, however.

Schiff said Sunday that Barr will have a "tarnished legacy" if he tries to "bury" any part of the report.

"If he were to try to withhold, try to bury any part of this report, that will be his legacy. And it will be a tarnished legacy," he said. "So I think there will be immense pressure not only on the department but on the attorney general to be forthcoming."
