Trump Media’s Soaring Share Price Masks Truth Social’s Internal Strife

The parent company of former President Donald J. Trump’s social media platform has soared on the stock market over the past month, despite growing turmoil behind the scenes.

In recent weeks, Trump Media & Technology Group has dismissed or pushed out at least three senior managers amid employee complaints about the leadership of Devin Nunes, the former Republican congressman who is chief executive, according to two people with knowledge of the matter.

The departures came after several employees anonymously sent a letter, which they described as a whistle-blower complaint, to Trump Media’s board a few weeks ago. The letter accused Mr. Nunes of being over-reliant on foreign contract workers and mismanagement. A copy of the letter was reviewed by The New York Times.

It was not clear whether the employees who were pushed out of Trump Media were involved in drafting the letter.

In the letter, the employees said that Mr. Nunes’s “directive” to hire foreign contractors was inconsistent with “the ‘America First’ principles we stand for.” Trump Media has looked to outsource some work to Cosmic Development, a technology company based in Canada that has operations in Macedonia and Serbia, said the two people.

Mr. Trump, who is the largest shareholder of Trump Media and the main draw for users on Truth Social, has talked on the campaign trail about imposing stiff tariffs on foreign goods and U.S. companies that outsource abroad.
