Is Pete Hegseth about to be "thrown under a bus"?

The Times Trump Report (I think this is genuine) is talking about a row between President Trump and  Pete Hegseth. I have no idea if this true.

Hmmm.. - NOT amateur radio

 Even if I was a Republican in the USA I would be concerned about this.

Hegseth shared Yemen attack details in second Signal chat, reports say - BBC News
