Giuliani has argued that Trump cannot be indicted by special counsel Robert Mueller in the Russian Federation investigation, but could face impeachment if he has done something wrong.
The report actually focused on decisions by former FBI Director James Comey in the 2016 investigation into Hillary Clinton's email server, well before Trump fired Comey and Mueller was named to take over the separate inquiry.
"When it's over, hey, he's the president of the United States, he retains his pardon power, nobody's taking that away from him", Giuliani said on CNN's "State of the Union" when asked whether Trump would pardon Manafort should he be convicted.
But Giuliani, in an appearance on CNN's State of the Union, left open the possibility that the president could take action when the Russian Federation inquiry was concluded if he determined that people had been "treated unfairly".
The president was responding to questions about the 568-page report released Thursday by the Department of Justice (DOJ) inspector general (IG) concerning the 2016 FBI investigation into former Secretary of State Hillary Clinton's use of a private email server and address to conduct official US diplomatic business.
He said the interview could be audio recorded, but that questions would need to be limited just to specific questions about "the heart of the probe" - allegations of collusion between Russian Federation and the Trump campaign. Susan Collins, R-Maine, said Sunday on CBS's "Face the Nation".
"There was no Russian Collusion". "If Manfort is convicted, will President Trump pardon him?" "I mean they have no Republicans". "Too bad they didn't look at Crooked Hillary like this".
Democrats said the inspector general's report provided no grounds to undermine Mueller's continuing investigation. "I think if I could get those pictures of them crying".
When asked if and when Mr. Trump would sit down with Mueller's team of investigators for an interview, Giuliani said he advised against it, but said his client is intent on providing his version of events.
Mr. Giuliani also set a deadline for the two top Justice Department officials.
The DOJ report pointed to the text messages Strzok sent to Lawyer Lisa Page, whom he was dating at the time, indicated "a biased state of mind".
The inspector general's report said it would continue investigating FBI officials who received tickets to sporting games and other things of value from reporters.
