President Trump fires back at new target: ESPN, after a controversial tweet by one of its anchors.

FOX's Jon Decker has more from the White House:

Days after ESPN anchor Jemele Hill tweeted said that "Donald Trump is a white supremacist who has largely surrounded himself w/ other white supremacists." President Trump fired back on Twitter:

Meanwhile, White House Spokeswoman Sarah Huckabee Sanders said she stands by her comment that the tweet is a fireable offense:

(Sanders) "ESPN has been hypocritical. They should hold anchors to a fair and consistent standard. ESPN suspended a long-time anchor Linda Cohn, not too long ago, for expressing a political viewpoint."

So far ESPN anchor Jemele Hill has apologized to the network, but not to the President.

At the White House, Jon Decker, FOX News.
