Federal prosecutors in the Southern District of New York (SDNY) are going to be investigating Donald Trump for the rest of his life, Above the Law co-editor-in-chief Elie Mystal explained on MSNBC's "All In" with Chris Hayes on Friday.

Mystal joined Hayes to discuss the latest news on Michael Cohen's cooperation with the U.S. attorney's office in Manhattan.

"What do you make of this?" Hayes asked.

"I think what it tells us is that SDNY is going to be part of Donald Trump's life -- for the rest of his natural life," Mystal predicted.

"SDNY is coming at Trump like syphilis -- it's going to make him crazy and it's never going away," he said, as Hayes laughed.

"SDNY is going to be here now, it's going here when Trump is out of office, it's going to be here for his family, it's going to be here for his grandkids if he's not careful," Mystal added.
