A White House official confirmed to Fox News that a teenaged employee with the nickname "Big Balls" has resigned from his post at the Department of Government Efficiency (DOGE), adding to the recent shakeup within the department.The now-former DOGE employee whose real name is Edward Coristine told Fox News Anchor Jesse Watters last month that his nickname originally came from his LinkedIn social media account."I use it as my LinkedIn username," Coristine told Watters, prompting laughter from the host as well as DOGE leader Elon Musk and the rest of his team at the interview."Well, people on LinkedIn take themselves super seriously, and theyre pretty averse to risk, and I was like, Well, I want to be neither of those things. So, I just, I set it and honestly, I didnt think anybody would notice," the DOGE employee continued, mocking the career-focused social media platform.DOGE STAFFING SHAKEUP AS ELON MUSK HANGS UP HIS HAT, WHITE HOUSE CONFIRMSA 19-year-old college student and software developer, Coristine was criticized by Democrats and liberal media pundits during DOGEs first few weeks of investigating wasteful and fraudulent spending in the federal government. Many were upset about the young, irreverently named government employee being given access to government records to pursue DOGEs work.During his interview with Watters, Coristine said he had been looking through U.S. Treasury Department payment computers and finding a multitude of outgoing payments from the federal government that lacked details about who they were going to and why."So, one of our initiatives is to root out fraud and waste, and to do that we started looking at the payment computers. And, as mentioned earlier, theres no accounting of what payments actually go to in the payment computer," Coristine said. "You look at a specific line item $20 million. Youre like, OK, what is this money going to? And for the majority of payment systems, its like, Well, we dont really know."FLASHBACK: TOP FIVE WILDEST MOMENTS FROM ELON MUSK'S DOGE TENURE AS IT COMES TO AN ENDHe continued, saying the system that distributes taxpayer money "literally has no checks and no accountability" to the American taxpayer, adding that it is a "huge vector for fraud, waste, and abuse."Coristines resignation comes less than a month after Musk departed from the agency.Musks departure was followed by the departure of several other staffers and special government employees at DOGE, which now includes Coristine.WHAT'S NEXT FOR DOGE AFTER ELON MUSK'S DEPARTURE?
