The argument appears remarkably vast and looks unlikely to prevail in court, said Paul Rosenzweig, a former member of Ken Starr’s investigation into former President Bill Clinton.

“It cannot be the case that, as a matter of law, everybody associated with the president is immune from criminal investigation while he’s the president. But taken at its fullest, that’s what the president’s argument is,” Rosenzweig told VICE News.

“I think it’s clear that the president is engaged in an effort to conceal and delay,” said Rosenzweig, now a senior fellow at the nonprofit R Street Institute. “It’s hard to say whether that’s because there’s something bad there, or because his entire life indicates a general instinct to conceal and delay.”
