Donald Trump’s arraignment, on Tuesday, spurred a media frenzy that dominated the news. But the week also revealed a vacuum of leadership in the current Republican Party. Some G.O.P. members voiced wholehearted support for Trump. Some chose to only condemn the prosecution, in order to appease his followers. Some said nothing at all. One lawmaker who has offered no comment on the indictment so far is Senate Minority Leader Mitch McConnell, who has been absent from the Senate since March 8th, when a fall sent him to the hospital with a concussion. Though the eighty-one-year-old senator has been weighing in on floor debates from rehab and his home, his absence has some colleagues worried about the future of the Party. In this week’s political roundtable, the New Yorker staff writers Susan B. Glasser, Jane Mayer, and Evan Osnos consider who is actually in charge of the Republican Party right now, and where they might be taking it.
