"While the United States is not currently in a position to join the endorsement, we continue to support the overall goals reflected" in the so-called "Christchurch Call," the White House said.
However, tech giants like Microsoft, Google, Facebook, Twitter, YouTube and Amazon have come out in the support of the movement which aims to address terrorist and violent content online via a nine-point plan.
"The terrorist attacks in Christchurch, New Zealand, in March were a horrifying tragedy. And so it is right that we come together, resolute in our commitment to ensure we are doing all we can to fight the hatred and extremism that lead to terrorist violence," the tech companies said in a joint statement on late Wednesday.
