Iranian hackers have laid the foundation to launch cyberattacks on electric grids, water plants, and health care and technology companies in the U.S., European countries, and in the Middle East, multiple senior U.S. officials tell NBC News' Courtney Kube, Carol E. Lee, Dan De Luce, and Ken Dilanian.

Why it matters: Iran has launched similar attacks before, like when it attacked U.S. banks and a dam in New York in what some security experts believe to have been in response to the 2010 Stuxnet attack on Iran, per Reuters. The U.S. is weighing whether striking back against Iran, if these extensive cyberattacks indeed come, would be the appropriate response. In preparation, the White House has reportedly readied sanctions against Tehran.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
