Lifelong Democrat and Harvard lawyer, Alan Dershowitz said on Tuesday that the Justice Department made very clear that sitting presidents cannot be “indicted, prosecuted, or tried while serving in office.”

The Harvard lawyer reminded everyone that the president must first be impeached and removed from office before he can be charged with a crime.

The Washington Post reported last week that Special Counsel Robert Mueller is currently investigating the president for obstruction of justice over his firing of former FBI Director James Comey. Subsequent reports contradicted this, saying that Mueller has not decided whether to investigate the president.

Regarding the investigation Dershowitz said, “The answer is ‘ish.’ He’s under investigation ‘ish.'”

“The president would be making a terrible mistake by getting into the weeds of arguing the facts rather than sticking to the conceptual constitutional issues,” Dershowitz said.
