This Tuesday, CNN’s Brian Stelter called out the White House press Secretary Sarah Sanders for bashing his network and saying it has such low ratings.

“Can’t imagine why @CNN has such low ratings when during the day they break from live coverage to show reruns,” she wrote on her Twitter account.

This was his response:

“It’s weird to see a White House press secretary talking about cable news ratings, AND she’s wrong about the facts. This was TVNewser’s headline just the other day: “CNN Has Its Second-Best August Ever.”
