Why?

That video was posted last May. From the city name and the channel number google takes you to the station's web page. Click on "weather," and play the current video. He's still there.

Chaff isn't chemtrails, and military use of chaff isn't a secret. Chaff is designed to be radar reflective, that's the whole point of it, so the fact that it shows up on radar isn't a secret either.

Contrails have been observed since the 1940s, the science of contrail formation is well understood, and photos and videos of contrails can be found from the 1940's onward. But even if you believe in chemtrails, chaff isn't chemtrails and isn't secret and what this guy said isn't revealing anything that would get him fired.
