Richard Sackler, whose family and company made billions from the sale of highly addictive opioid painkillers, has now patented a new and potentially lucrative treatment for opioid addiction, the Financial Times reports.

Why it matters: More than 200,000 people have died from prescription opioid overdoses since 1999. And Purdue Pharma, which the Sackler family owns privately, has become a poster child for the opioid crisis because of the way it aggressively marketed OxyContin despite rampant abuse of that drug.

The details: Richard Sackler is listed on the patent for a new formulation of buprenorphine, one of the leading treatments for opioid addiction, per the FT. Buprenorphine is administered through a tablet or strip that dissolves in patients' mouths; Sackler's version says it would dissolve faster.

Go deeper: The New York Times investigated Purdue and the Sackler family's role in the opioid crisis. So did the Los Angeles Times.

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.
