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 that appears to be back on.

These graphics explain what the Democrats would need to do to flip the Senate and House of Representatives

A turning point in Donald Trump’s second term will soon arrive. On 3 November, voters across the US will decide whether to keep the president’s Republican allies in control of Congress, or return Democrats to the majority.

Many indicators of voter sentiment suggest the Democrats are favored to take back control of the House of Representatives, and potentially the Senate. Winning either would be a significant victory for the party and give it the power to block Trump’s legislative agenda and more aggressively investigate his administration.
