New law could create $3.7 trillion tsunami. (Ad)

During a meeting in Washington D.C., Jeff Brown discovered a bold initiative. He calls it “President Trump’s Project MAFA,” and it could soon return America to a “new” gold standard. The Trump administration, Wall Street, and Silicon Valley are all pushing it forward.
