Sen. Chuck Grassley said expects special counsel Robert Mueller will release a report on his investigation into Russian interference in the 2016 election “within a month.”

"Within a month, if we see it," the Iowa Republican said while speaking to radio talk show host Hugh Hewitt on Tuesday.

Grassley, who serves on the Judiciary Committee and was its chairman last term, said he wants as much of the report made public as possible. He also expressed doubt that Mueller would find any collusion or conspiracy between Russia and President Trump's 2016 campaign.

"I look at it from this standpoint. I don’t care what the report says," Grassley said. "We paid $25 million, maybe $35 million to do it, and the public ought to know what their $25 or $35 million bought. And except for national security and privacy of individuals, those would be understandably redacted, everything else, I think, ought to be out."

Trump said in a CBS interview that aired Sunday it would be up to his attorney general whether the report would be made public. William Barr, Trump’s nominee to be attorney general, said at his confirmation hearing last month that Mueller’s findings will be confidential but he supports releasing them to the public.

"My objective and goal is to get as much as I can of the information to Congress and the public," he said.

Neither Mueller or anyone on his team have publicly discussed when the investigation could wrap up and the findings could be released.
