The CDC said in new guidelines Sunday that gatherings of 50 or more people should be postponed or canceled for the next eight weeks to curb the spread of the novel coronavirus.

What they're saying: "Large events and mass gatherings can contribute to the spread of COVID-19 in the United States via travelers who attend these events and introduce the virus to new communities," the CDC said in a statement. "Examples of large events and mass gatherings include conferences, festivals, parades, concerts, sporting events, weddings, and other types of assemblies."

Exceptions: The CDC said the recommendation does not apply to "the day to day operation of organizations." These include schools and businesses.

Yes, but: At least 57,000 K-12 schools across the U.S. have closed or will close temporarily in response to the outbreak.

Hygiene precautions: The CDC said in its statement events "of any size" should only be continued if they can adhere to guidelines for "protecting vulnerable populations, hand hygiene, and social distancing." 

The big picture: COVID-19 has killed at least 69 people and infected more than 3,700 others in the United States.

Trump campaign goes all in on Pennsylvania

The president's campaign is placing more importance on Pennsylvania amid growing concern that his chances of clinching Wisconsin are slipping, Trump campaign sources tell Axios.

Driving the news: Pennsylvania, which has 20 electoral votes, twice Wisconsin's number, actually has been trending higher in recent public and internal polling, a welcome development for the campaign.

Inside Biden's Supreme Court strategy

Joe Biden’s closing argument will shift to a dominant emphasis on health care, turning the looming Supreme Court fight into a referendum on coverage and pre-existing conditions, officials tell Axios.

Why it matters: Biden aides believed they were winning when the race was about the coronavirus pandemic. Now they plan to use the Supreme Court opening as a raucous new field for a health care fight, returning to a theme that gave Democrats big midterm wins in 2018.
