The Bill and Melinda Gates Foundation pledged $150 million for its coronavirus relief efforts on Wednesday, on top of the $100 million committed in February.

The big picture: Tech giants like Google and Facebook have donated hundreds of millions to COVID-19 relief efforts.

Catch up quick: The $250 million in total is being used to support African and South Asian countries, vaccine development, models to project the course of COVID-19, emergency aid for students after school closures, and investing in medical supplies, the Gates Foundation says.

What they're saying: "COVID-19 doesn’t obey border laws. Even if most countries succeed in slowing the disease over the next few months, the virus could return if the pandemic remains severe enough elsewhere,” Bill Gates said in a statement on Wednesday.

  • “The world community must understand that so long as COVID-19 is somewhere, we need to act as if it were everywhere. Beating this pandemic will require an unprecedented level of international funding and cooperation.”

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.

U.S. vs. Google — the siege begins

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.
