It's been clear for more than a week that Donald Trump lost the US election, but he still hasn’t acknowledged the fact. On the contrary, he's actively denying it. And he's doing some things that a President who's just lost an election, would never normally do. He's fired a handful of top defence and intelligence officials and replaced them with loyalists. It’s prompted speculation there's a coup of sorts in the works. In this edition of ABC podcast The Signal, they consider whether this a serious attempt to hang on to power or something else altogether. The podcast features Kim Hoggard, non-resident fellow at the US Studies Centre and a former senior official in the Reagan and Bush Snr administrations.
