DONALD Trump’s under-fire defence chief hit back with a foul-mouthed blast yesterday after full details of his part in an astonishing battle plan security breach were released.

The US President had said no sensitive information was leaked when a journalist was added by mistake to a group chat of top officials planning attacks on Houthi rebels in Yemen earlier this month.

But The Atlantic editor Jeff Goldberg responded by publishing a list of aircraft and timings US Defence Secretary Pete Hegseth had posted via the Signal app.

Mr Hegseth then tried to dismiss it, saying the “so-called war plans include no names, no targets, no locations, no units, no routes, no sources, no methods, no classified information”.

He added: “Those are some really s****y war plans.

“This only proves one thing: Jeff Goldberg has never seen a war plan.”

Several lawmakers called for Mr Hegseth to be axed.

Secretary of State Marco Rubio admitted that “someone made a big mistake”.

Meanwhile, UK Defence Secretary John Healey took a subtle dig at the US after the chat criticised “freeloading Europe”.

He said: “The thing about being close allies and good friends is if you’ve got concerns or challenges, you raise them, but you don’t do so in public.”
