Trump Media's stock, identified by its ticker symbol 'DJT', experienced a decline of 4.1% in pre-market trading amid a contentious exchange between the company's CEO and major financial entities. The CEO, in a letter to NASDAQ, accused short sellers of market manipulation, a claim that was sharply criticized by Ken Griffin's Citadel. Citadel dismissed these allegations and labeled the CEO a 'proverbial loser.' In response, Trump Media has advised shareholders against lending out their shares, intensifying its campaign against short selling practices.
