The inquiry forced counterintelligence investigators to evaluate whether Trump was a potential threat to national security, and they also sought to determine whether Trump was deliberately working for Russian Federation or had unintentionally been influenced by Moscow. The story says it is unclear whether Mueller is pursuing the counterintelligence case.
"Campaigns leak polling data all the time", Giuliani said, before decrying the focus on the investigation as a "joke" and "total mockery" that "only happens because 75 percent of the press hates Trump".
The grand jury empaneled by the special counsel has been extended for another six months, however, signaling that the probe may continue beyond the winter.
Giuliani also tried to shrug off the revelation accidentally made by former Trump campaign chief Paul Manafort's lawyers in an unredacted court filing that Manafort had apparently shared internal campaign polling with a colleague with reported ties to Russian intelligence.
President Trump has denied any collusion with Moscow and has called the Mueller investigation a "witch hunt".
Trump has disputed the allegations from the dossier, which was funded by the Clinton campaign and DNC.
Special counsel Robert Mueller took over the inquiry upon his appointment May 17, 2017, just over a week after Trump fired Comey. "We weren't convinced they had any questions they don't know the answer to".
The officials told the newspaper that after Comey was sacked in May 2107, they become concerned when Trump tied the firing of Comey to the Russian Federation investigation. He also says his now-former lawyer, Cohen, lied to get a lighter sentence in NY.
The lawyer, Michael Cohen, has been sentenced to three years in prison for multiple crimes, including felony violations of campaign finance laws he undertook, prosecutors alleged, under Trump's direction.
Mueller's final report can be finished within months and Giuliani is hoping he can use executive privilege to get his hands on it before the public.
The newspaper said it's not clear whether Mueller is still looking into that matter.
