Kris Jenner -- I Put Weatherman On Blast ... But I Didn't Get Him Fir

Kris Jenner has a lot of pull in Los Angeles ... but just because she unleashed her wrath on a longtime LA weatherman over social media, doesn't mean she got him fired despite all the rumors.

Sources close to the situation tell TMZ ... Kris had nothing to do with Garth Kemp's departure from his 17-year-long position as the KABC weatherman ... he actually left to pursue his dreams of being a voice over actor.

Rumors were flying around like crazy that Garth was forced out by head honchos at his ABC affiliated station because of Kris.

Back in June KJ put him on blast to millions of her Instagram followers ... calling him a bully after he talked smack about Kim and Kanye not having talent. We're told Kris only fired back on IG ... she never called the station and didn't want him to get fired.

Mama bird defending her family is one thing, but forcing a guy to get fired is something completely different.
