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. Allegations have surfaced that he shared sensitive military details, including flight timings of Yemen air strikes, via Signal. This incident comes after Hegseth previously criticized Hillary Clinton for her use of a private email server. Similar incidents involving Hegseth and Signal chats have recently come to light, raising concerns about security protocols within the Pentagon.
