“I expect very little will come out because Director Mueller has told the country his report is his testimony,” Conway added, citing frequent remarks by Mueller that his 400-page report on the findings of his investigation were all he intended to say about the probe before he reached an agreement to testify.

“He told the whole country within the last 6 to 8 weeks that he’s retiring to private sector, this is over and he has nothing further to add,” Conway said.

Mueller’s testimony was previously set for July 17 before congressional leaders announced it would be delayed to July 24, which will allow members more time to question him.

The extra time, Conway said on Sunday, may prove to be a boon to Republican members by giving them the opportunity to question Mueller about the cost of the investigation.
