Rep. Kevin YoderKevin Wayne YoderProgressive group targets GOP moderates on immigration GOP cautious, Dems strident in reaction to new indictments GOP rep bringing widow of slain Indian immigrant to State of the Union MORE (R-Kan.) on Thursday doubled-checked that his sign language interpreter was authentic before speaking at a briefing on deaf awareness in the Capitol, according to a report. 

 “Do I need to double-check though that the sign language interpreter actually is an interpreter?" he asked during remarks, The Washington Post reported.

"Looks like she’s legit. Okay. If she starts just making stuff up let me know," Yoder told a small audience, who reportedly broke out in laughter. 

Yoder’s joke came after news that the sign language interpreter during President Obama’s speech at Nelson Mandela’s memorial service used fake hand gestures, later claiming he suffered from schizophrenia

The interpreter, Thamsanqa Jantjie, said that he is certified to sign, but he slipped into an altered state during the ceremony, according to reports. He also said he had become violent during some previous episodes.
