Facebook says it'll flag posts from 'newsworthy' politicians that break its rules, including those from US President, Donald Trump. 

Several major advertisers have joined a call to boycott the social network over its approach to 'hate speech'.

Facebook's CEO Mark Zuckerberg had previously shown reluctance to act against Donald Trump.

"I committed to reviewing our policies ahead of the 2020 elections. That work is ongoing, but today I want to share some new policies to connect people with authoritative information about voting, crack down on voter suppression, and fight hate speech.

"The 2020 elections were already shaping up to be heated -- and that was before we all faced the additional complexities of voting during a pandemic and protests for racial justice across the country."

On Friday evening he Zuckerberg  insisted he's taking action to 'help everyone stay safe' and 'informed'.
