Donald Trump has threatened to veto a major military funding bill unless Congress abolishes a liability law protecting social media firms regularly accused of bias by the president.
Section 230 of the Communications Decency Act gives immunity to tech companies such as Facebook and Twitter from legal action on content posted by users.
Both platforms have found themselves the target of incandescent fury from Trump in recent weeks after they began attaching disclaimers to social media posts by the president that claimed he had lost last month’s election due to voter fraud.
Trump has doubled on a months-old push to abolish the statute in response — a move that has been backed by his congressional allies.
“Section 230… represents a serious threat to our national security and the integrity of the elections,” the president tweeted on Tuesday night.
