Trump posted on his website Truth Social early Wednesday that “THIS IS A GREAT TIME TO BUY!!!” as stock markets were tanking A few hours later, Trump announced a 90-day suspension of additional tariffs against some countries, triggering a historic stock market rebound A group of US senators on Friday urged the government’s markets watchdog to investigate whether President Donald Trump or White House insiders broke securities laws ahead of his dramatic reversal on global tariffs. The six Democrats — led by Massachusetts progressive Elizabeth Warren — noted in a letter to the Securities and Exchange Commission (SEC) that Trump posted on his website Truth Social early Wednesday that “THIS IS A GREAT TIME TO BUY!!!” as stock markets were tanking. A few hours later, Trump announced a 90-day suspension of additional tariffs against dozens of countries, triggering a historic stock market rebound and the best day for the S&P 500 since the recovery from the 2008 financial crisis. “We urge the SEC to investigate whether the tariff announcements… enriched administration insiders and friends at the expense of the American public,” senators wrote in a letter to regulators at the Securities and Exchange Commission. The letter urged the SEC to probe whether “any insiders, including the president’s family, had prior knowledge of the tariff pause that they abused to make stock trades ahead of the president’s announcement.” Trump signed his Truth Social post with the letters “DJT” — both his initials and the stock market abbreviation for his media company, Trump Media & Technology Group. The company’s shares closed up 21.67 percent on Wednesday. The senators called on the SEC to investigate whether the president, his donors or other insiders had engaged in market manipulation, insider trading or other violations of securities laws.
