He’s referring to what he said when the Senate acquited Trump after he was impeached by the House.

Trump’s lawyers are trying to argue that he can’t be prosecuted by the courts for actions he took as president unless he is first impeached and convicted in Congress for those actions. When Trump was impeached and acquitted in 2021, McConnell stated that Congress can’t impeach him as he is no longer in office and that the matter is an issue for the criminal justice system.

As shit as McConnell is, he is not confused with his dates right now, and his statements from 2021 are very relevant to this case and have been discussed in the news a lot recently.

I’m also not sure what’s wrong with your quoted text. Nothing about it sounds confused to me.

US News (Feb 14, 2021): Text of McConnell’s Speech

President Trump is still liable for everything he did while he was in office, as an ordinary citizen, unless the statute of limitations has run, still liable for everything he did while in office, didn’t get away with anything yet – yet.

We have a criminal justice system in this country. We have civil litigation. And former presidents are not immune from being held accountable by either one.
