>> President Donald Trump on Monday, railing against the Russian investigation on Twitter, saying what he calls the With Hunt is quote, rapidly losing credibility. And warning prosecutors under Special Counsel Robert Mueller that quote, there is a court system in place that actually protects people from injustice. The Twitter storm a possible references to statements by Trump's lawyer, former New York Mayor Rudy Giuliani, over the weekend who raised the possibility that the President might not comply if Mueller issues a subpoena for Trump to appear before a grand jury.
Jan Wolfe is reporting this story.>> Both sides here have reasons to not to want to resort to a subpoena. A subpoena would involve a protracted court battle and that's something that Mueller probably doesn't want. He wants to act quickly. But ultimately if it got to that point, Bob Mueller would have the upper hand here.
The Supreme Court said in an important case involving Richard Nixon that the President can be forced to comply with the subpoena when there's no other real way of getting relevant information.>> Giuliani's comments, the latest salvo in high stakes negotiations over a possible interview of Trump, as Mueller's probes Russia's interference in the 2016 race and possible collusion by Trump's campaign.
>> Lawyers on both sides of the political aisle, they understand why Giuliani might not want the President to sit for an interview. Often the subject of investigation gets themselves in more trouble by covering up whatever offense is initially being investigated, and Trump has a tendency to go off-script and contradict himself.
So he's trying to protect his client here, and has concerns about an interview, and is engaging in some hardball tactics to maybe get by Mueller to just give up on actually interviewing the President.>> Speaking to ABC News, Giuliani also said Trump could take the Fifth Amendment if he did testify, invoking his right to remain silent and avoid self-incrimination.
