MSNBC analyst: Giuliani is stalling, and Mueller doesn't need a sit down with Trump to prove his case

In a wide-ranging discussion with host Katy Tur, MSNBC contributor and former U.S. attorney Chuck Rosenberg expressed doubts that Special Counsel Robert Mueller would even need to talk to Donald Trump at all.

"Rudy Giuliani's been flip-flopping on it faster than I can flip a dime in the air," began Tur, referring to ongoing speculation about whether or not Trump will eventually sit for an interview with the special counsel. "At what point does Mueller run out of patience and realize this is just a stalling tactic, if he thinks it is, and ends up subpoenaing the president?"

Rosenberg agreed, saying "I think the Mueller team has long ago, many, many months ago, realized you can't rely on what Mr. Giuliani says and it's a stalling tactic."

The real question, asked Rosenberg, is "does the Mueller team absolutely have to talk to the president? They'd like to. It would be nice, but they don't have to." He listed several circumstances in which federal investigations concluded without speaking to a specific target or subject.

"If the question is 'can you conclude the investigation without talking to the president', the answer is 'absolutely'," said Rosenberg.
