Hunter Biden is scheduled to speak at the Democratic National Convention on Thursday night, during the curtain-raiser to his father's high-profile acceptance speech as the Democratic nominee.

Why it matters: Trump and his allies have sought to exploit the controversy over Hunter Biden's paid board position at Ukrainian gas company Burisma — held while his father was the Obama administration's point man on Ukraine — to damage Joe Biden.

  • Trump's efforts to pressure the Ukrainian government to investigate the Bidens culminated in his impeachment and subsequent acquittal in the Senate.
  • Hunter will speak with his sister, Ashley Biden, to tell DNC audience members about their father.

Reality check: Hunter’s role with Ukrainian energy company Burisma did raise conflict-of-interest concerns at the time. But there is no evidence that the former vice president committed "corruption" of any kind in the country while his son worked at Burisma, as Trump and his allies have claimed.

What to watch: People close to President Trump told Axios' Alayna Treene in March that Trumpworld planned to hit Biden hard with attacks over the controversy involving his son if he gained front-runner status.

The final debate

Watch for President Trump to address Joe Biden as “the big guy” or “the chairman” at tonight's debate as a way of dramatizing the Hunter Biden emails. Hunter's former business partner Tony Bobulinski is expected to be a Trump debate guest.

The big picture: Trump's advisers universally view the first debate as a catastrophe — evidenced by a sharp plunge in Trump’s public and (more convincingly for them) private polling immediately following the debate.

Finally, a real debate

A more disciplined President Trump held back from the rowdy interruptions at tonight's debate in Nashville, while making some assertions so outlandish that Joe Biden chuckled and even closed his eyes. A Trump campaign adviser told Axios: "He finally listened." 

The result: A real debate.

Biden looks to stem oil "transition" furor amid GOP attacks

Joe Biden's campaign is looking to blunt attacks in response to his comments in Thursday night's debate about a "transition from the oil industry," as Republicans look to make the remarks a liability in the closing days of the race.

Driving the news: Biden campaign spokesperson Bill Russo, in comments circulated to reporters Friday afternoon, said the former VP "would not get rid of fossil fuels," but wants to end subsidies.
