Donald Trump launched a Twitter war of a different sort Thursday, picking a fight with the online platforms that helped to shape his political career.
A feud that, should it escalate, could curtail free speech in the United States and even run afoul of North America's new trade pact.
Angered by Twitter's decision to place fact-check flags on two of his recent tweets, Trump signed an executive order Thursday authorizing a review of Section 230 of the U.S. Communications Decency Act.
Act is considered a cornerstone of the modern-day internet that protects online platforms from being held liable for third-party content on their sites.
