A warning for this episode - it covers details of a murder and an execution that some might find distressing. In this episode of Guardian Australia’s US politics podcast, co-hosts Jonathan Yerushalmy and Reged Ahmad examine what happened when the state of Tennessee tried to execute prisoner Christa Pike. They also look at the controversy over taxpayer-funded ads promoting US president Donald Trump, midterm AI attack ads and the Elon Musk-Trump bromance appears to be back on.
