The Department of Justice’s impending lawsuit against Google has narrowed to focus on the company’s power over internet search, a decision that could set off a cascade of separate lawsuits from states in ensuing weeks over the Silicon Valley giant’s dominance in other business segments.

As the $26 billion blockbuster merger between T-Mobile and Sprint teetered this summer, Makan Delrahim, the head of the Justice Department’s antitrust division, labored to rescue it behind the scenes, according to text messages revealed in a lawsuit to block the deal. Delrahim connected company executives with the Federal Communications Commission and members of Congress.

Cisco Systems agreed to pay $8.6 million to settle claims that it sold video surveillance technology that it knew had a significant security flaw to federal, state and local government agencies. Cisco will pay civil damages in connection with software that it sold to various government agencies, including Homeland Security, the Secret Service, the Army, the Navy, the Marines, the Air Force and the Federal Emergency Management Agency.

The murder of Jamal Khashoggi, a columnist for The Washington Post, has focused the world’s attention on the kingdom’s intimidation campaign against influential voices raising questions about the darker side of the crown prince. The young royal has tightened his grip on the kingdom while presenting himself in Western capitals as the man to reform the hidebound Saudi state. Saudi operatives have mobilized to harass critics on Twitter, a wildly popular platform for news in the kingdom since the Arab Spring uprisings began in 2010.

Deputy Attorney General Rod Rosenstein announced new charges against 12 Russian intelligence officers accused of hacking the Democratic National Committee, the Clinton presidential campaign, and the Democratic Congressional Campaign Committee. Rosenstein said the Russians involved belonged to the military intelligence service GRU. They are accused of a sustained cyberattack against Democratic party targets, including its campaign committee and Hillary Clinton's campaign.

The Justice Department’s inspector general, facing increasing political pressure from Republicans in Congress and Attorney General Jeff Sessions, said that his office would investigate the surveillance of a former Trump campaign official. The inspector general, Michael E. Horowitz, said he would examine whether law enforcement officials complied with the law and departmental policies in seeking permission from the Foreign Intelligence Surveillance Court to wiretap the former campaign adviser, Carter Page.

Apple, complying with what it said was a request from Chinese authorities, removed news apps created by The New York Times from its app store in China late in Dec. The move limits access to one of the few remaining channels for readers in mainland China to read The Times without resorting to special software.

The government began blocking The Times’s websites in 2012, after a series of articles on the wealth amassed by the family of Wen Jiabao, who was then prime minister, but it had struggled in recent months to prevent readers from using the Chinese-language app. Apple removed both the English-language and Chinese-language apps from the app store in China on Dec 23. Apps from other international publications, including The Financial Times and The Wall Street Journal, were still available in the app store.

Social media companies are under increasing scrutiny for the amount of hate speech that thrives on their platforms, especially since the presidential election. Now, Twitter has unveiled several new measures to curb the online abuse, though the changes are unlikely to be far-reaching enough to quiet the company’s critics. Twitter said it was making it easier for its users to hide content they do not wish to see on the service and to report abusive posts, even when those messages are directed at other users. The company has given its support teams training to better identify mistreatment on Twitter.

Google and Facebook have faced mounting criticism over how fake news on their sites may have influenced the presidential election’s outcome. Those companies responded by making it clear that they would not tolerate such misinformation by taking pointed aim at fake news sites’ revenue sources. Google kicked off the action saying it will ban websites that peddle fake news from using its online advertising service. Facebook updated the language in its Facebook Audience Network policy, which already says it will not display ads in sites that show misleading or illegal content, to include fake news sites. Taken together, the decisions were a clear signal that the tech behemoths could no longer ignore the growing outcry over their power in distributing information to the American electorate.

It has been six months since the Justice Department backed off on demands that Apple help the FBI break the security of a locked iPhone. But the government has not given up the fight with the tech industry. Open Whisper Systems, a maker of a widely used encryption app called Signal, received a subpoena in the first half of 2016 for subscriber information and other details associated with two phone numbers that came up in a federal grand jury investigation in Virginia. The subpoena arrived with a court order that said Open Whisper Systems was not allowed to tell anyone about the information request for one year.

Technology companies contend that court-imposed gag orders are being used too often by law enforcement and that they violate the Bill of Rights. The companies also complain that law enforcement officials are casting a wide net over online communications — often too wide — in their investigations. Justice Department officials, for their part, argue that these gag orders are necessary to protect developing cases and to avoid tipping off potential targets. The officials say that they are simply following leads where they take them.
