Republican Kentucky Sen. Rand Paul on Wednesday formally invited President Donald Trump to attend the Senate’s impeachment trial against him, as his guest.

Paul tweeted a photo of a ticket to the Senate gallery, where spectators can watch the impeachment trial, saying he would love to have Trump as his guest during “this partisan charade.”
