According to two individuals who spoke to the president earlier this summer about Harris, Trump made a point of trashing the senator for saying last year that based on the Mueller Report findings, under the next Democratic administration the Department of Justice would have “no choice” but to pursue obstruction of justice charges against Trump. “I’ve seen prosecution of cases based on much less evidence,” Harris, who was announced this week as presumptive 2020 Democratic presidential nominee Joe Biden’s VP pick, told NPR.

One of the sources said the president recently mocked Harris for making a big deal about the DOJ potentially prosecuting him after he leaves office, saying she wanted to play “tough.” Trump, this source recounted, said he thought she was just “bluffing” and that she and other Democrats are just craving another “witch hunt.” In the same conversation, the president also made fun of Harris’ call at a Democratic debate late last year to have Trump kicked off Twitter.

“Criminal prosecution of President Trump? [Kamala] must be smoking something,” John Dowd, a lawyer who represented Trump for nearly a year of Special Counsel Robert Mueller’s Russia probe, said in a brief interview on Thursday. “The American people are very smart. They figure these things out pretty easily. There’s not going to be any prosecution of the president after he leaves office.”
