US Defence Secretary Pete Hegseth has come under scrutiny for reportedly using a ‘dirty line’ in his Pentagon office, bypassing security protocols to access apps like Signal, where he allegedly shared sensitive military details about Yemen air strikes, including flight timings. This incident is particularly notable as Hegseth had previously criticized Hillary Clinton for using a private email server. Recently, similar incidents involving Hegseth and Signal chats have surfaced, raising concerns about the security of sensitive information within the US Department of Defense.
