"The President is not going to issue pardons in this investigation".
"Well I don't think it exonerates him", Giuliani stated when asked about Trump's comments.
Manafort was sent to jail last week after a federal judge revoked his house arrest over allegations of witness tampering in the Russian Federation investigation.
Giuliani responded, "Not in this investigation".
"Doesn't mean that anybody should rely on it", Giuliani added later in his answer, noting other presidents who he said had issued pardons "in these political investigations".
Trump hasn't made a decision yet, and his legal team will spend the weekend doing research and reading through a Justice Department inspector general's report to determine whether they can make a case that Mueller's investigation is invalid because of findings of bias at the FBI, Giuliani said.
"Please, listen to what I'm saying, and the President: The big signal is, nobody's been pardoned yet".
"I'm very proud because he's got that spirit", Giuliani said of Trump.More news: High Heat and Humidity Leading Into Next Week
After calling for an investigation, Giuliani said that Mueller's probe into possible ties and coordination between the Trump campaign and Kremlin is "illegal" and "unethical".
Trump has not yet spoken to Mueller as part of the probe, and Giuliani suggested Sunday that he should not do so under oath - pointing to Trump's recent backpedaling on how he characterized his son Donald Trump Jr.'s 2016 meeting with a Russian lawyer as evidence of why it's hard to sort out "a lot of different recollections".
Finally, during an interview with CNN's Chris Cuomo, Giuliani confirmed that Trump will not pardon anyone, but explained the president also will not relinquish his pardon power.
Mueller is reportedly seeking to conclude the investigation this summer, according to The Washington Post.
"Of course it's wrong to lie, it breaks one of the commandments, I think", Giuliani replied before arguing Trump's "distinction is a correct one".
Later Sunday, Giuliani said on CBS' Face the Nation that he would continue to push for such an internal review as a condition in the ongoing negotiations with Mueller who is seeking an interview with Trump in the Russian Federation inquiry. Oh, I see, there was no Russian Collusion, so now they look for obstruction on the no Russian Collusion.
In a subsequent interview on Sunday with CBS's "Face The Nation" show, Giuliani said the Mueller probe should face both an internal government investigation by the Justice Department's inspector general and a grand jury probe. "He is not considering it and he will not even entertain thinking about it until after the investigation has been completed", he said.
