Tensions over the Supreme Court nomination of Brett Kavanaugh and sexual assault allegations against him have driven the Senate to a heightened security posture, as some lawmakers fended off protesters and others saw their personal information released online.

Demonstrators, many of them sexual assault survivors, have flooded the Capitol in recent days to share their stories and urge Republican senators to reject the Kavanaugh nomination. Close-up exchanges between protesters and senators, including in elevators and at airports, have led to additional security measures, especially for Senate Judiciary Committee members.

On Tuesday, Judiciary Republicans John Kennedy of Louisiana and Lindsey Graham of South Carolina were protected by uniformed Capitol Police. Graham was also accompanied by Deputy Sergeant-at-Arms James Morhard, one of the top law enforcement officials on Capitol Hill. Last week, teams of uniformed officers were moving alongside Jeff Flake of Arizona and Judiciary Chairman Charles E. Grassley of Iowa.

Lawmakers who receive full-time protective details from the Capitol Police include the speaker, majority and minority leaders in both chambers, and the whips in both parties. Other members may receive added protection in response to specific threats, but otherwise spend much of their time outside the Capitol complex, including in their home districts, without bodyguards.

Protests weren’t the only concern. Someone with an IP address matching the Capitol complex added Majority Leader Mitch McConnell’s home addresses in Kentucky and Washington D.C. to his public Wikipedia page.
