A former member of President Trump's legal team has confirmed that Robert Mueller raised a possibility last month that could lead to a long legal battle: a presidential subpoena. John Dowd, who led the Trump team's response to the Mueller investigation until his resignation in March, tells Reuters that Mueller warned that a subpoena for Trump to appear before a grand jury was possible after Trump's attorneys said the president was not obliged to speak to investigators. Dowd says he told the special counsel: "This isn't some game. You are screwing with the work of the president of the United States." Two weeks after the meeting, Dowd left Trump's legal team, which is now being led by Rudy Giuliani.
Experts say that if Trump is subpoenaed, the legal fight could go all the way to the Supreme Court. Insiders tell the Washington Post that after the possibility was raised, Trump's legal team asked for more information on what Mueller wanted to discuss with the president and turned the information into the leaked list of 49 questions. The Post's sources say Trump is still so angry about the raid on attorney Michael Cohen's offices that he's highly unlikely to agree to a Mueller interview, though Giuliani says it's still a possibility. "Hopefully we're getting near the end. We all on both sides have some important decisions to make," the former New York City mayor says. "I still have a totally open mind on what the right strategy is." (Mueller has an "intriguing" question about Paul Manafort.)
