    President Trump announces three-day tariff delay on Truth Social

President Trump announced on Truth Social that the U.S. will postpone a proposed 50% tariff on $20 billion in Canadian imports for three days. The announcement, made less than two hours before the deadline, followed a deal intended to resume construction of the Keystone pipeline project. The pipeline is designed to transport oil from Canada to the U.S.

The move comes as the U.S., Canada, and Mexico face uncertainty regarding the United States-Mexico-Canada Agreement (USMCA), a free trade pact that facilitates duty-free trade. While the USMCA governs hundreds of billions of dollars in trade, President Trump has stated he does not care about its renewal. No specific details regarding the new pipeline agreement have been released by either government.

In legal developments, a trial began Tuesday against Meta, the parent company of Facebook and Instagram. Four states allege the company intentionally designed addictive platforms and misrepresented risks to young users. A whistleblower and former Meta employee, Arturo Bejar, testified that internal studies showed young people faced higher risks of harmful content than the company publicly acknowledged. Meta has denied the allegations, stating it implemented policies to mitigate known risks.

For social media users and families, the Meta trial could fundamentally change the legal obligations of technology companies toward minors. The four states involved are seeking penalties that could reach $1.4 trillion, a figure roughly equal to Meta's total equity value on the Nasdaq. A ruling against the company could lead to mandatory changes in how algorithms function for young users and how social media platforms disclose safety data to the public.

What happens next depends on the three-day tariff extension and the ongoing testimony in the Meta trial. Whistleblower Arturo Bejar is expected to continue his testimony today, and Meta CEO Mark Zuckerberg may be called to the stand at a later date. On the trade front, it remains unknown if the three-day delay will lead to a permanent resolution or if the 50% tariffs will be enacted after the new deadline passes. Additionally, the Trump administration moved Tuesday to repeal environmental regulations that prohibited logging and mining on millions of acres of public forest land.
