Nikolai Vitti, superintendent of Detroit's public school system, said that the drinking water will be turned off in schools citywide when students return due to increased copper and lead levels in the water.

Why it matters: The infrastructure of Detroit's public schools have been deteriorating for decades and is facing billions of dollars in debt, the New York Times reports. With no funding to rebuild its public schools in hand, there's no telling when the water will be turned back on.

By the numbers:
  • The city conducted water quality tests on 24 schools this year and found that at least 16 of them had increased copper or lead levels in the water — sometimes both.
  • In total, the city has 45,000 students attending 106 schools. Fountain water will be unavailable to all of them.
  • The city estimates it would take $500 million to completely update the infrastructure in all schools.
  • The city's school system is facing $3.5 billion in debt in combined operating and capital liabilities.

The backdrop: In 2016, Detroit found that the water in 19 schools was contaminated, the Free Press reports. That testing took place at the same time as the Flint water crisis, which also investigated lead contamination.

Yes, but: The root cause of Flint's health crisis had to do with the lack of adequate treatment of its water supply, whereas in Detroit, the problem may be antiquated infrastructure in the school buildings.

Chief Justice John Roberts was hospitalized overnight after a fall on June 21, a Supreme Court spokesperson confirmed to the Washington Post on Tuesday.

Why it matters: Speculation regarding justices' health — given their lifetime appointments — always runs rampant, and this incident may have not been made public if the Post hadn't "received a tip."

Congress vs. tech's gang of four

The CEOs of tech's four leading giants will defend their industry's growing concentration of power from critics on both right and left who view them as monopolists when they testify, most likely virtually, before Congress on July 27.

Why it matters: The joint appearance by Facebook's Mark Zuckerberg, Apple's Tim Cook, Amazon's Jeff Bezos and Google's Sundar Pichai will mark a historic collision between the leaders of an industry that has changed the world and political leaders who believe those changes have harmed democracy and individual rights.

The three topics generating the most intense interest online are the coronavirus, racial injustice and foreign policy, according to data from NewsWhip provided exclusively to Axios — and all are issues that are working against President Trump right now.

Why it matters: Storylines in Trump's populist sweet spot that carried the news cycle for much of his presidency — immigration, trade, a strong economy — have fallen away during the pandemic.
