John McCain's Arizona Senate seat, which he'd occupied for more than three decades, will remain vacant until after his burial at the U.S. Naval Academy Cemetery in Maryland, an aide to Gov. Doug Ducey told The Arizona Republic.

What's next: Ducey, a Republican, will appoint McCain's successor to serve until a special election in 2020. The winner of that election would complete the remainder of McCain's term, which ends in January 2023.

Who Ducey might choose:

  • Cindy McCain, the late senator’s 64-year-old wife, leads the list of potential successors, per the Republic. She is a philanthropist, a business leader and an advocate against human trafficking — and she has represented McCain at public events in recent months since his cancer diagnosis.
  • Kirk Adams, a former state lawmaker and Ducey’s chief of staff, is also on the Republic's shortlist. Adams ran an unsuccessful bid for Congress in 2012.
  • Other potential choices on their shortlist: Barbara Barrett, the state’s first female gubernatorial candidate; former Sen. Jon Kyl; former Reps. Matt Salmon and John Shadegg; Karrin Taylor Robson, a member of the state Board of Regents; and Eileen Klein, whom Ducey appointed as state treasurer in April.

Flashback: Jean Carnahan was appointed to a Missouri Senate seat in 2001 after her husband, former Missouri Gov. Mel Carnahan, was posthumously elected.

GNC Holdings, the Pittsburgh-based nutritional supplements retailer, received bankruptcy court approval to sell itself to China’s Harbin Pharma for $770 million, although the deal still faces U.S. political pressures over how GNC customer data is protected.

Why it matters: It's a reminder that the U.S.-China merger mess goes well beyond smartphone apps, with Sen. Marco Rubio asking for a CFIUS review.

Tallying Trump's climate changes

Reproduced from Rhodium Climate Service; Chart: Axios Visuals

The Trump administration's scuttling or weakening of key Obama-era climate policies could together add 1.8 gigatons of carbon dioxide equivalent to the atmosphere by 2035, a Rhodium Group analysis concludes.

Why it matters: The 1.8 gigatons is "more than the combined energy emissions of Germany, Britain and Canada in one year," per the New York Times, which first reported on the study.
