The people of Bougainville voted Saturday on whether they want their island to become the world's newest country.

What to watch: Results are expected by Dec. 20, and most in Bougainville (pop. ~300,000), currently an autonomous region of Papua New Guinea, are expected to vote for independence.

Why it matters: The FT notes that the referendum has "sparked a scramble for political influence among foreign mining companies, which want to establish operations in an area that contains copper and gold reserves estimated to be worth tens of billions of dollars."

  • Flashback: "Between 1972 and 1989 a company controlled by Rio Tinto, the Anglo-Australian miner, operated the massive Panguna copper and gold mine on the island, generating huge profits and almost half of Papua New Guinea’s export income. But the activity caused serious pollution and tensions to flare with locals, which erupted into civil war in 1989 and forced Panguna to close."

What to watch: The referendum is non-binding, and Papua New Guinea's leaders seem reluctant to grant independence.

Robert Mueller speaks out on Roger Stone commutation

Former special counsel Robert Mueller responded to claims from President Trump and his allies that Roger Stone was a "victim" in the Justice Department's investigation into Russian interference in the 2016 election, writing in a Washington Post op-ed published Saturday: "He remains a convicted felon, and rightly so."

Why it matters: The rare public comments by Mueller come on the heels of President Trump's move to commute the sentence of his longtime associate, who was sentenced in February to 40 months in prison for crimes stemming from the Russia investigation. The controversial decision brought an abrupt end to the possibility of Stone spending time behind bars.
