Beleaguered ABC News was reeling Thursday morning after having to correct its latest anti-Trump error — an on-screen caption Wednesday afternoon that falsely stated that Paul Manafort, Donald Trump’s ex-campaign chief, pleaded guilty to five charges of manslaughter.
ABC quickly apologized for the error – saying there “is no excuse” — and an ABC spokesperson said the network is still “investigating” what went wrong. But ABC News sources tell Fox News that the false report was a “practice chyron” that had likely been maliciously written by a hostile ABC News employee (a chyron is a TV news term for words that appear on the lower third of the screen).
