(CNN) President Donald Trump should not sit down for an interview with special counsel Robert Mueller, his former campaign manager Corey Lewandowski said.

"I haven't spoken to the President about it directly, but if he did ask my opinion ... my political advice would be not to sit down with Bob Mueller," Lewandowski said Thursday on CNN's "Erin Burnett OutFront."

Trump's personal lawyer Rudy Giuliani -- who has been negotiating with the Mueller team over interview parameters -- told Politico on Thursday that Trump and his lawyers will decide whether the President will meet with Mueller in a "week to 10 days," his latest estimate on when a final decision could come.

Lewandowski thinks such an interview would involve more unintended risks for Trump than benefits.
