CNN s Don Lemon on Monday warned people against falling for GOP spin as the impeachment inquiry into President Donald Trump moves into a new phase this week.

The CNN Tonight host previewed the upcoming public impeachment hearings by cautioning how Trumps allies will likely attempt to twist developments all in an effort to keep you from zeroing in on the one thing that really matters.

The one question that matters is this: Did the president abuse his power? And is it worthy of impeachment or removal from office? That is the substance. Keep your focus on the substance, Lemon said. Everything else is a distraction.

Dont follow red herrings, like the president demanding to out the whistleblower, he continued, later adding, It doesnt matter who the whistleblower is. Weve moved way beyond that.

Lemon said the focus should be on the substance of the complaint and whether it matches the testimony of witness after witness after witness after witness. It does.

Dont follow the red herrings, he said again. Dont chase the shiny object. Dont fall for the okey-doke. Dont be distracted. Focus on the substance, on the facts.
