Here it is as storified by Willard Cheng (storified with an interview with Vergel Santos), in a two-minute news feature for “The World Tonight” a few minutes ago on the ABS-CBN News Channel
Where the President is dishing out false claims as fact, should the news media interrupt the President’s live news briefing by cutting away then fact-checking?

In this afternoon’s ten-minute interview, my answer was (paraphrasing it) Yes. We should consider the example of the world’s leading news organizations when President Trump’s false claims in a live news briefing was cut away and interrupted with fact-check. But if you’re too shy to do this, you can strengthen the fact-checking by having an election watchdog resource person on-standby to deliver the factcheck in order not to overburden the news anchor in having to justify why they have to correct the President etc.
That’s one. Other production techniques I suggested are (if you’re too shy to cut away the President’s live news briefing) : You can run char-gens or computer-generated crawlers or text at the bottom of the screen (crawlers) while the President is talking, presenting facts or stating the need for factchecking, simultaneously with the President’s live news briefing (this requires a really good news executive producer). Another production technique is to run an inset box with graphics simultaneously with the President’s live news briefing. And the last one of course is — if it’s about the elections — always have an independent election watchdog resource person on standby so you can cut away to the resource person for fact-checking — making sure your resource person is qualified, concise, competent, and will present nothing but numbers, statistics, data and facts.
The last one, have an election watchdog resource person on-stand-by was the one used in the news feature (30-second soundbyte).
Interesting questions from the ABS-CBN News Channel. Thank you for provoking this discussion! (see embedded video, will pixelate in a few seconds, credits: as stated in the video and freeze-frame)

Interesting questions from the ABS-CBN news team and anchor Ron Cruz in this afternoon’s interview at 5pm: “When the news subject like the President (in this case, Trump) is announcing false “data” as fact, e.g., “if you count legal votes, I win”, should the news media cut the President’s live news briefing and and fact-check? How should the local media see this (cutting the President’s live media briefing to fact-check)?” The answers i gave are… My answers were along the theme of the role and duty of the news media as purveyor of truth; that when the news media wittingly or unwittingly provides too much air time to any news subject disseminating falsehood without fact-checking, it is giving credence to the falsehood. Then i provided various production techniques of presenting the fact-check simultaneously (in case the news organization is “too shy” to interrupt), etc. Then I was asked whether our local news media does this, and should do this (should it interrupt the President in his live news briefing to fact-check) … My answer, referencing cutting the President live during his live news briefing is… our news media does not really do this (does not really INTERRUPT the President in his live news briefing by cutting it then fact-checking it), some news media organizations may be “too timid” to do this, and to be fair, the news media has been subjected to censorship such as the ABS-CBN shutdown, and to harassment such as baseless lawsuits against Rappler, etc. and that, we can follow the lead of fact-checking in this manner (of interrupting the President in his live news briefing by actually cutting it) or we can use other ways of presenting a live simultaneous or contemporaneous fact-check of the President ( such as the ones i suggested, aware of the struggles of news media organizations, i provided examples of production techniques as alternatives in presenting a simultaneous LIVE fact-check of a LIVE NEWS BRIEFING by the President), let me search for a video of this afternoon’s live interview.

Here is the position of colleagues on the matter whose views I share (on INTERRUPTING THE PRESIDENT IN HIS LIVE NEWS BRIEFING in order to fact-check)

To quote from the news article: “[J]ournalist-educator Danilo Arao […] shared the lessons […] from US coverage of elections. […] ‘[I]t is time to rethink the news media organizations’ live coverage of Duterte’s ramblings,’ Arao wrote.” https://t.co/yjoHLxf13L

LESSON FROM US COVERAGE: When ABC, CBS and NBC decided to stop the live coverage of Trump’s press briefing, it was because of his baseless claims of voter fraud. In the Philippines, it is time to rethink the news media organizations’ live coverage of Duterte’s ramblings.
