多名知情人士向哥伦比亚广播公司新闻透露，那些正配合美国司法部针对前中情局局长约翰·布伦南是否曾向国会撒谎一事展开的刑事调查的前高级情报官员和联邦调查局官员，已于上周末被传唤至华盛顿特区的大陪审团作证。
据哥伦比亚广播公司此前报道，负责该案的职业检察官于上周晚些时候被解职后不久，司法部便任命特朗普的保守派盟友乔·迪杰诺瓦正式接管针对布伦南的刑事调查。
迪杰诺瓦是特朗普总统的坚定支持者，此前曾代表特朗普竞选团队试图推翻2020年总统选举结果，但最终失败。
消息人士称，这些合作证人最快将于本周前往大陪审团作证。其中许多人原本就配合调查，且在周末收到大陪审团新的传唤令之前，就已安排好与联邦调查局特工和检察官进行面谈。
法律专家向哥伦比亚广播公司表示，突然调整合作证人的自愿面谈安排，要求其亲自到大陪审团作证的做法不同寻常。按照惯例，这类面谈通常在大陪审团程序之外进行，之后特工会向大陪审员转述证人在宣誓后所作陈述的细节。
华盛顿特区的大陪审员近来越来越多地拒绝起诉那些被普遍认为具有政治动机的案件涉案人员，此次举措可能是迪杰诺瓦为穷尽一切调查手段而采取的行动。
Cooperating witnesses in criminal probe of ex-CIA Director Brennan subpoenaed to testify before grand jury, sources say

Former senior intelligence and FBI officials who are cooperating with the U.S. Justice Department’s criminal probe into whether former CIA Director John Brennan lied to Congress were subpoenaed over the weekend to testify before a grand jury in Washington, D.C., multiple sources familiar with the matter told CBS News.
The subpoenas went out shortly after the Justice Department appointed conservative Trump ally Joe DiGenova to formally take over the criminal investigation into Brennan after the career prosecutor handling the case was removed late last week, CBS previously reported.
DiGenova is a staunch loyalist of President Trump who previously represented his campaign in its failed efforts to overturn the results of the 2020 presidential election.
The cooperating witnesses are scheduled to appear before the grand jury as soon as this week, sources said. Many of them have been cooperating with the probe and were already scheduled to sit down for interviews with FBI agents and prosecutors before the new grand jury subpoenas came out over the weekend.
The decision to abruptly reschedule the voluntary interviews from cooperators and ask for in-person grand jury testimony is unusual, legal experts told CBS. Customarily such interviews are conducted outside of the grand jury, and agents later provide details from them to grand jurors about what the witnesses told them under oath.
The move could be an effort by DiGenova to use every avenue possible, after grand jurors in Washington D.C. have increasingly declined to indict targets in cases that were widely perceived as politically motivated.
