The bipartisan leaders of the Senate Homeland Security and Governmental Affairs Committee have asked for a review of assaults against personnel in DHS, including in the Border Patrol, Customs and Border Protection and other components with law enforcement responsibilities.

Sens. Ron Johnson, R-Wis., and Claire McCaskill, D-Mo., asked the department’s IG for a report in the wake of reports of what they called a “substantial” increase over the last year against Border Patrol agents. They asked for a review of such assaults and the measures that DHS “has taken to mitigate the threats faced by CBP law enforcement personnel in the field.”

The senators are seeking data going back to 2010 on the location and type of assault; days lost to injury; trends that have emerged; the methods DHS uses to track such information; use of tactical and de-escalation training; and other measures that could be taken to improve safety.
