Reps. Robert Garcia (D-Calif.) and Dan Goldman (D-N.Y.) are demanding an update on the Department of Homeland Securitys efforts to quash racism and bigotry within its ranks after HuffPost reporting revealed widespread use of anti-immigrant slurs among Border Patrol agents.

A series of communications disclosed to HuffPost under the Freedom of Information Act earlier this year showed Border Patrol agents, including several in supervisory roles, routinely using the derogatory slur tonk. The term has an uncertain origin, but Border Patrol agents who use it widely believe that it comes from the sound of bashing a migrant in the head with a heavy-duty flashlight. The records also showed Border Patrol agents joking about killing migrant children by donating faulty car seats to a charity drive or spiking Rice Krispy Treats with cyanide.
