NEW YORK (CBSNewYork.com) — While Mayor Bill de Blasio and health officials were giving updates on New York City’s first Ebola case Friday, the focus turned to another person in the room: The sign language guy.

The signer, who was seated to the right of the mayor, was enthusiastically signing throughout the press conference.

It appeared as if he was talking to another signer who was seated in the audience.

Some even questioned whether he was a legitimate sign language interpreter.

The Twitterverse soon noticed and tweets started taking the Internet by storm.

In true New York fashion, no one on my timeline seems fazed by #Ebola and everyone's poking fun at the sign language interpreter. — Victoria Rossi (@VictoriaRossi) October 24, 2014

It turns out, Jonathan Lamberton is certified as a Deaf interpreter and sat down with DHN, a news station that incorporates American Sign Language, spoken English and captions in all of its broadcasts, to discuss the rumors and why people mistakenly thought he was making it up.
