At least three times in the last year the Capitol Police officers have left loaded firearms in various bathrooms around the Capitol Building. The incidents have involved the security details for top congressional leaders, and a child came in contact with one of the lost firearms, Roll Call reports.

When a member of Senate Majority Leader Mitch McConnell's security detail left his Glock and magazine stuffed in the toilet seat cover holder of a Capitol Visitor Center bathroom stall, a CVC worker found the gun, according to a source familiar with the Jan. 29 incident and two other disturbing instances when Capitol Police left loaded firearms in problematic places.

A 7- or 8-year-old child visiting the Capitol with his parents found the next loaded Glock lost by a dignitary protection officer, according to the source. A member of the security detail for John A. Boehner, R-Ohio, allegedly left the firearm in the bathroom of the Speaker's Suite on March 24.
