PHILADELPHIA — Demo-crats arrived at their nominatingconvention on Sunday under acloud of discord as DebbieWasserman Schultz, the chair-woman of the Democratic Na-tional Committee, abruptly saidshe was resigning after a trove ofleaked emails showed party offi-cials conspiringto sabotage thecampaign ofSenator BernieSanders of Ver-mont.

The revela-tion, along withsizable pro-Sanders pro-tests here in thestreets to greetarriving dele-gates,threatened to undermine the deli-cate healing process that followedthe contentious fight between Mr.Sanders and Hillary Clinton. Andit raised the prospect that a con-vention that was intended toshowcase the Democratic Party’soptimism and unity, in contrast tothe Republicans, could be marredby dissension and disorder.

The day also veered extraordi-narily into allegations, not easilydismissed, that Russia had a handin the leaks that helped bringdown the head of an American po-litical party.

Despite those concerns, Dem-ocrats are hoping that focusing onDonald J. Trump, the Republicannominee, will galvanize the partyto rally around Mrs. Clinton, andon Sunday those efforts received amajor boost when Michael R.Bloomberg, the former Republi-can and independent mayor ofNew York, said he would endorseher.

In her resignation statement,Ms. Wasserman Schultz, a repre-sentative from Florida, said shewould continue to fight for Mrs.Clinton from the sidelines.

“I know that electing HillaryClinton as our next president iscritical for America’s future,” Ms.Wasserman Schultz said in astatement. “I look forward to serv-ing as a surrogate for her cam-paign in Florida and across thecountry to ensure her victory.”

She added, “Going forward, thebest way for me to accomplishthose goals is to step down asparty chair at the end of this con-vention.”

FREMONT, Calif. — ElonMusk, the chief executive of TeslaMotors, sat in a glass-walled con-ference room here last week in thecompany’s auto factory. Aroundhim, workers and robots werebuilding the $70,000 luxury vehi-cles that have redefined how peo-ple think about electric cars.

But autos are just one of Mr.Musk’s many projects. A SouthAfrican-born billionaire and en-trepreneur, he is the top investorin the country’s largest providerof rooftop solar power, runs a pri-vate rocket company, and in a blogpost last week pledged to create aride-sharing car service and bat-tery-powered trucks and buses.

And then there is his plan forthe world’s largest battery factory.The so-called Gigafactory, in Ne-vada, is to be unveiled this week.

“What’s going to be really crazyabout the Gigafactory is not just

that it’s giant,” Mr. Musk said.“You can’t change the world withtiny factories that move slowly,”he said. “We need big factorieswith high-velocity output.”

Scale and speed are watch-words for Mr. Musk and his save-the-world view of business, which

MSAKEN, Tunisia — His ownparents were so frightened by hisviolence that they kicked him outwhen he was 16. Desperate, by thetime he was 19, they dragged himto a psychiatrist, who prescribedan antipsychotic drug, a tranquil-izer and an antidepressant.

“There were the beginnings of apsychosis,” the doctor, HamoudaChemceddine, recalled in an inter-view in the Tunisian city ofSousse, looking over his notesfrom that visit in August 2004. “Hewasn’t someone who was living inthe real world.”

In France, he even created aFacebook page with an alter ego,listing his profession as a “profes-sor of salsa dancing” and display-ing a mock image of NicolasSarkozy, the former French presi-dent, in drag.

That man — a 31-year-old deliv-ery driver, Mohamed LahouaiejBouhlel — trained his violenttendencies on a crowd watchingfireworks along the French Rivi-era on July 14, running over hun-dreds of people and killing 84 in arented cargo truck during BastilleDay celebrations in Nice.

Olympic officials said on Sun-day that all Russian athletes weretainted by the country’s state-rundoping system and would not beallowed to compete in the Sum-mer Games unless they convincedindividual sports federations oftheir innocence.

With just 12 days before theGames begin, the InternationalOlympic Committee said in astatement that “all Russian ath-letes seeking entry to the OlympicGames Rio 2016 are considered tobe affected by a system subvert-ing and manipulating the antidop-ing system.”

The showdown between Russiaand Olympic officials was richwith intrigue beyond the playingfields in Rio de Janeiro. PresidentVladimir V. Putin of Russia hadsuggested the doping allegationswere politically motivated andmeant to undermine his country’sstanding in the world. TheOlympic leadership had been un-der pressure to expel a majorsports power for perpetrating oneof the most expansive doping pro-grams in history and corruptingresults at the Summer and WinterGames.

In the end, Russian officials re-ceived a reprieve, in their view.The Russian flag and at leastsome of the country’s athletes willbe a part of the Rio Olympics. Theburden now shifts to sports feder-ations to vet Russia’s individualOlympic candidates.

Antidoping officials and someathletes had publicly lobbied for ablanket ban on the entire Russiandelegation. Anything short of that,they argued, was too soft a punish-ment for what the Olympic com-mittee president, Thomas Bach,had called a “shocking new di-mension in doping” with an “un-precedented level of criminality.”

“This may not please every-body on either side,” Mr. Bach saidSunday, repeating his desire tobalance “the individual justice towhich every human being is enti-

SAN FRANCISCO — Yahoowas the front door to the web foran early generation of internet us-ers, and its services still attract abillion visitors a month.

But the internet is an unforgiv-ing place for yesterday’s greatidea, and Yahoo has now reachedthe end of the line as an independ-ent company.

The board of the Silicon Valleycompany has agreed to sell Ya-hoo’s core internet operations andland holdings to Verizon Commu-nications for $4.8 billion, accord-ing to people briefed on the mat-ter, who were not authorized tospeak about the deal before theplanned announcement on Mon-day morning.

After the sale, Yahoo share-holders will be left with about $41billion in investments in the Chi-nese e-commerce company Al-ibaba, as well as Yahoo Japan anda small portfolio of patents.

That compares with Yahoo’speak value of more than $125 bil-lion, reached in January 2000.

Marissa Mayer, Yahoo’s chief

executive, is not expected to joinVerizon, but she is due to receive aseverance payout worth about $57million, according to Equilar, acompensation research firm.

Verizon and Yahoo declined tocomment on the deal.

Founded in 1994, Yahoo was oneof the last independently operatedpioneers of the web. Many of thosegroundbreaking companies, likethe maker of the web browser Net-scape, never made it to the end ofthe first dot-com boom.

But Yahoo, despite constantmanagement turmoil, kept grow-ing. Started as a directory of web-sites, the company was soon doingmuch more, offering searches,email, shopping and news. Thoseservices, which were free to con-sumers, were supported by adver-tising displayed on its variouspages.

For a long time, the modelworked. It seemed as if everycompany in America — andacross much of the world —wanted to reach people using the

WASHINGTON — An unusualquestion is capturing the attentionof cyberspecialists, Russia ex-perts and Democratic Party lead-ers in Philadelphia: Is Vladimir V.Putin trying to meddle in theAmerican presidential election?

Until now, that charge, with itseerie suggestion of a Kremlin con-spiracy to aid Donald J. Trump,has been only whispered.

But the release on Friday ofsome 20,000 stolen emails fromthe Democratic National Commit-tee’s computer servers, many ofthem embarrassing to Demo-cratic leaders, has intensified dis-cussion of the role of Russian in-telligence agencies in disruptingthe 2016 campaign.

The emails, released first by asupposed hacker and later byWikiLeaks, exposed the degree towhich the Democratic apparatusfavored Hillary Clinton over herprimary rival, Senator BernieSanders of Vermont, and trig-gered the resignation of DebbieWasserman Schultz, the partychairwoman, on the eve of the con-

vention’s first day.Proving the source of a cyber-

attack is notoriously difficult. Butresearchers have concluded thatthe national committee wasbreached by two Russian intelli-gence agencies, which were thesame attackers behind previousRussian cyberoperations at theWhite House, the State Depart-ment and the Joint Chiefs of Stafflast year. And metadata from thereleased emails suggests that thedocuments passed through Rus-sian computers. Though a hackerclaimed responsibility for giving
