A handful of letters in the most recent Journal of the American Medical Association question whether the apparent "sonic attack" against U.S. personnel stationed in Cuba happened — or at least second-guess the level of academic rigor behind that diagnosis.

What they're saying: A total of 10 doctors across across four JAMA letters say that researchers — particularly via a study published in JAMA this past March — gave unduly short shrift to the possibility that embassy employees suffered instead from mass hysteria.

From the letters:

  • "The key is whether the patients had knowledge that others were becoming ill or knew that there was a suspicion that sonic weapons were involved."
  • "Based on the evidence presented thus far, mass psychogenic illness cannot be discounted."
  • "Although diagnostic caution is warranted, functional neurological disorders are common genuine disorders that can affect anyone, including hardworking diplomatic staff."
  • "It is inappropriate to conclude without baseline data that any of the 6 patients presented were truly impaired."

The other side: The authors of the initial JAMA study — the one that supported the idea of a sonic attack — responded, saying they agree more research would be helpful but that some of the criticisms don't hold water.

  • One of the doctors who questioned their findings, for example, has previously identified "a preponderance of female participants" as a characteristic of mass hysteria. (Only about half of the Americans in Cuba were women.)

The clock is ticking for tens of thousands of anxious airline employees, who face mass reductions when the government's current payroll support program expires on Sept. 30.

Where it stands: Airline CEOs met Thursday with White House Chief of Staff Mark Meadows, who said President Trump would support an additional $25 billion from Congress to extend the current aid package through next March.

House Democrats ask DOJ watchdog to probe Durham's Trump-Russia investigation

Four Democratic House committee chairs on Friday asked the Justice Department's inspector general to launch an "emergency investigation" into whether Attorney General Bill Barr and U.S. Attorney John Durham, his appointee, are taking actions that could "improperly influence the upcoming presidential election."

Catch up quick: Last year, Barr tapped Durham to conduct a sweeping investigation into the origins of the FBI's 2016 Russia probe, after he and President Trump claimed that it was unjustified and a "hoax."
