SEN. MARK WARNER (D-Va.) hosted a dinner Friday night for more than 100 guests at his house on Martha’s Vineyard as part of the DSCC’S annual Majority Trust retreat. OVERHEARD: Warner, the vice chairman of the Senate Intelligence Committee, joking to the crowd: “If you get me one more glass of wine, I’ll tell you stuff only Bob Mueller and I know. If you think you’ve seen wild stuff so far, buckle up. It’s going to be a wild couple of months.”
