根据国家公共广播电台（NPR）的说法，当地时间4月21日，一名美国官员透露，白宫开始寻找新的国防部长。新闻发布后不久，白宫说，NPC的报告以寻找新的国防部长是“假新闻”。据报道，由于新闻发布，NPC面临着资金中断。美国国防部长皮特·黑西（Pete Hegsey）最近被指控在私人团体聊天中泄露机密信息。 On April 20, the local time, according to the New York Times and other American media, citing resources familiar with this matter, Hegseyth leaked information about the upcoming US military air welges in Yemen in a private "signal" chat group on March 15. New York Times believes that the newly exposed "group chand door "incidents allowed the outside world to evaluate Hegsey's management and judgment capabilities.
