Trump wipes out trillions overnight… (Ad)

Is there anybody more powerful than Donald Trump right now? In a single tariff announcement, he wiped out nearly $5 trillion in wealth from the S&P 500 and $6.4 trillion from the Dow Jones… Not to mention the countless trillions of dollars lost in every market around the world… leaving the major political powers scrambling in fear of Trump’s next move.

Whether you take some of that wealth for yourself depends on if you watch this controversial exposé
