President Donald Trump, finally facing his impeachment trial, needs Mitch McConnell more than ever. It’s a defining moment for both men. They started their relationship unevenly three years ago but have since fallen into an easy partnership. The House is poised to transmit the articles of impeachment against Trump this week. On Monday, McConnell and Senate Republicans were trying to decide whether to seek a motion to simply dismiss the charges, as Trump suggested, once the trial starts. That’s just one of the crucial decisions that McConnell will make or at least influence.
