People are bullish about the role big tech can play in health care. In a PwC survey, majorities said they’re at least somewhat confident tech companies will be able to: improve patient satisfaction, reduce costs, simplify health care, and make personal health care information more accessible to patients

Yes, but: It hasn’t happened yet. The most significant progress so far would be on that last front, making personal health data more accessible — that’s where Apple is focusing a lot of its health care energy, and the early reviews are generally pretty positive. But even that is still in its early stages.

The latest: Apple is trying to get Medicare Advantage insurers to offer subsidized Apple Watches to seniors, for use as health trackers, CNBC’s Christina Farr reports.

Other tech companies have made moves into the health care world, none splashier than Amazon buying PillPack, but they’ve largely been pretty traditional moves.

The big picture: So far, Silicon Valley seems to be better at getting a piece of the health care system than changing it.

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.

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."
