Well, this was bound to happen.

During the inaugural meeting Thursday of the new Congressional Deaf Caucus, at least one lawmaker cracked a joke at the expense of the official interpreter for this week's memorial service for former South African President Nelson Mandela.

Taking the stage at the meeting in the basement of the Rayburn House Office Building, Rep. Kevin Yoder (R-Kan.) greeted the dozens of people gathered in the room and then stopped.

“Do I need to double-check though that the sign language interpreter actually is an interpreter?" Yoder asked. Turning to an interpreter standing next to him, he said: "Looks like she’s legit. Okay. If she starts just making stuff up let me know."
