Senate Majority Leader Mitch McConnell, R-Ky., could seek to hold the Senate in session longer each week to keep vulnerable incumbent Democrats off the campaign trail.

McConnell this month began threatening Senate Democrats with longer workweeks if they continue to slow-walk the confirmation of President Trump’s nominees. Marc Short, White House point man for legislative affairs, told a small gathering of Republican donors this week that the majority leader plans to use this tactic in the weeks ahead to squeeze Democrats running for re-election in red states.
