复杂句分析
News outlets were nearly unanimous in rejecting new rules imposed by Defense Secretary Pete Hegseth that would leave journalists vulnerable to expulsion if they sought to report on information-classified or otherwise-that had not been approved by Hegseth for release.
that 指代 new rules
expulsion 驱逐
新闻机构几乎一致反对由国防部长Hegseth强加给新闻记者的新规：新规会让记者处于被容易驱逐的处境，一旦记者想报道一些没有被Hegseth批准发布的机密或者其他信息。
classified confidential 差别
classified 一般指政府、军队等分等级的保密信息；
confidential 多用于商业、公司中的保密信息
