Hong Kong, Alberto Salazar, Jessye Norman: Your Tuesday Briefing – The New York Times

(Want to get this briefing by email? Here’s the sign-up.)

Good morning.

We’re covering the shooting today of a protester in Hong Kong, new research on the consumption of red meat, and the death of the opera star Jessye Norman.

The Justice Department said last week that it was looking into whether other countries “played a role in the counterintelligence investigation directed at the Trump campaign.” Current and former Justice officials said that it was not necessarily illegal or untoward for Mr. Trump to ask world leaders to cooperate.

Background: The F.B.I. began examining the Trump campaign’s ties to Russia after Australian officials reported that Russian intermediaries had offered damaging information about Hillary Clinton.

Related: Access to a transcript of Mr. Trump’s call with the Australian leader was limited. Similarly, the July discussion with Ukraine’s president was placed in a highly restricted computer system. Here’s how it works.

Why it matters: The call with Mr. Morrison again shows Mr. Trump using federal law enforcement to aid his political prospects.

Yesterday: House Democrats subpoenaed Mr. Trump’s personal lawyer, Rudolph Giuliani, in their impeachment inquiry. And Senator Mitch McConnell, the majority leader, said a Senate trial would be unavoidable if the House impeached Mr. Trump.

The Daily: Today’s episode is about the history of impeachment.

An enormous military parade in Beijing today commemorated 70 years of Communist Party control, hours before antigovernment demonstrations in Hong Kong. One protester was shot, a first in the city’s monthslong political crisis, according to pro-democracy lawmakers. Here are the latest updates.

Closer look: The anniversary parade, which included 100,000 performers and 15,000 soldiers, was among the largest in modern Chinese history. See photographs here.

Background: The People’s Republic of China was founded on Oct. 1, 1949, after the Communist Party, led by Mao Zedong, defeated the Nationalist Party in a civil war. Read more about the history of the celebrations.

Go deeper: Under its leader, Xi Jinping, the Communist Party has recast China’s history, playing down the traumas of the Mao era, including the tens of millions who died of starvation.

Progressive Democratic presidential candidates have proposed the biggest changes to tax policy in more than a century.

Bernie Sanders — who has said, “I don’t think that billionaires should exist” — and Elizabeth Warren have both outlined plans that target the wealthy to help pay for social programs like tuition-free college, universal child care and “Medicare for all.”

Critics argue that a wealth tax would cripple economic growth and sap the motivation of entrepreneurs.

Background: The debate comes amid rising income inequality in the U.S., which reached its highest level last year since the government began tracking it in 1967. The top 0.1 percent now controls about a fifth of the country’s wealth.

Eating less beef and pork has little to no health benefits, according to research published on Monday that contradicts a bedrock of almost all dietary guidelines.

The study is among the largest evaluations of red meat consumption ever conducted, and may influence future recommendations.

Public health officials have criticized the findings, the latest in a series of reversals involving salt, fats, carbohydrates and more. Scientists at Harvard warned that the conclusions “erode public trust in scientific research.”

Go deeper: Here are 10 other findings that contradict medical wisdom.

Another angle: “The prospect of a renewed appetite for red meat also runs counter to two other important trends: a growing awareness of the environmental degradation caused by livestock production, and longstanding concern about the welfare of animals,” our reporter writes.

If you have 14 minutes, this is worth it

Deutsche Bank. North Korea’s hacking of Sony Pictures. The House Intelligence Committee’s investigation of President Trump. In each of these cases, Val Broeksmit, above, has taken secret documents — and an uncanny nose for scandal — to the center of the news.

Mr. Broeksmit, an unemployed rock musician, has also been an important, sometimes maddening, source for our finance editor, who writes: “We might wish our whistle-blowers were stoic, unimpeachable do-gooders. In reality, to let you in on a journalistic secret, they’re often more like Val Broeksmit.”

Here’s what else is happening

U.S.-North Korea talks: The two countries will resume a long-stalled dialogue over the North’s nuclear weapons program this weekend, a North Korean diplomat said today.

Pay for college sports stars: Gov. Gavin Newsom of California signed a first-of-its-kind measure to allow amateur athletes to strike endorsement deals and hire agents.

Congressman resigns: Representative Chris Collins, a fourth-term Republican from western New York, stepped down before an expected guilty plea today in an insider-trading case.

Voting in Afghanistan: The two main contenders in last weekend’s presidential election both claimed they were ahead after counting had barely begun. It’s expected to take two weeks for results to emerge.

Doping penalty: Alberto Salazar, a coach of some of the world’s top distance runners, has been barred for four years for doping violations, the U.S. Anti-Doping Agency announced.

Snapshot: Above, relatives consoled Zahida Jan in August after her brother was detained during the Indian government’s crackdown in the Kashmir region. Our photographer spent four weeks documenting a population that feels unsettled, demoralized and furious.

In memoriam: Jessye Norman, a Grammy Award-winning soprano, was a towering figure on the operatic, concert and recital stages. She died on Monday at 74.

Late-night comedy: “Let’s not pull Australia into this,” James Corden said. “They’re our cool, laid-back friends. You don’t ask them to get involved in your politics; you ask them to D.J. your pool party.”

What we’re reading: This Twitter thread of people recounting times they gushed over a celebrity’s dog before noticing the celebrity holding the leash. “It’s hilarious — and we could all use a laugh,” writes Andrea Kannapell, the briefings editor.

Now, a break from the news

Cook: Linguine with clam sauce is a simple evening meal. (Our Five Weeknight Dishes newsletter has more recommendations.)

Eat: In a new monthly feature, our columnist offers a complete and easy dinner party menu.

Watch: The opening shot of “The Irishman,” Martin Scorsese’s latest crime story, evokes a canonical sequence from “Goodfellas” and turns it inside out.

Go: On a road trip across Cuba, music is everywhere, and each region moves to its own rhythm.

Smarter Living: There’s evidence that exposure to two types of chemicals found in plastics — phthalates and bisphenols — can affect health, especially during fetal development and children’s first years. So use metal or glass containers and a HEPA-filtered vacuum, and avoid vinyl products like shower curtains. For toys, wood or silicone is safer than plastic.

And we have guidance on how to wash stuffed toys — which is especially important after a child has been sick.

And now for the Back Story on …

Warnings that carbon dioxide might warm the Earth go back further than you might think.

An experiment demonstrating the warming power of the gas was presented in 1856 at a meeting of the American Association for the Advancement of Science in Albany.

The amateur scientist who performed and wrote up the experiment: Eunice Newton Foote, an inventor and women’s rights campaigner.

Her experiment was straightforward. To see whether releasing carbon dioxide into the atmosphere would increase temperatures, she used thermometers and two glass tubes — one rich in carbon dioxide, the other less so.

She laid out both tubes in the sun to see whether one might heat up more. We know the answer: The one with more CO2 did.

Her findings were presented at the Albany meeting by a man, in keeping with the era’s limitations on women. But her work was published, and three years later it was replicated and advanced by the Irish scientist John Tyndall.

The work created the foundational understanding of the greenhouse effect, which informs climate research to this day.

That’s it for this briefing. See you next time.
