Sophisticated surveillance, once the domain of world powers, is increasingly available on the private market. Smaller countries are seizing on the tools — sometimes for darker purposes.

Federal prosecutors are examining whether foreigners illegally funneled donations to President Trump’s inaugural committee and a pro-Trump super PAC in hopes of buying influence over American policy. The inquiry focuses on whether people from Middle Eastern nations — including Qatar, Saudi Arabia and the United Arab Emirates — used straw donors to disguise their donations to the two funds. Federal prosecutors in Manhattan are investigating whether President Trump’s 2017 inaugural committee misspent some of the record $107 million it raised from donations. The criminal probe by the Manhattan

Russians working for a close ally of President Vladimir Putin engaged in an elaborate campaign of “information warfare” to interfere with the midterm elections, federal prosecutors said in unsealing a criminal complaint against one of them. The woman, Elena Alekseevna Khusyaynova, of St. Petersburg, was involved in an effort “to spread distrust toward candidates for US political office and the US political system,” prosecutors said.

The New York Times is asking the Foreign Intelligence Surveillance Court to unseal secret documents related to the wiretapping of Carter Page, the onetime Donald Trump campaign adviser at the center of a disputed memo written by Republican staffers on the House Intelligence Committee. The motion is unusual. No such wiretapping application materials apparently have become public since Congress first enacted the Foreign Intelligence Surveillance Act in 1978.

A pair of White House officials played a role in providing House Intelligence Committee Chairman Devin Nunes (R-CA) with the intelligence reports that showed that President Donald Trump and his associates were incidentally swept up in foreign surveillance by American spy agencies. The revelation that White House officials assisted in the disclosure of the intelligence reports — which Chairman Nunes then discussed with President Trump — is likely to fuel criticism that the intelligence chairman has been too eager to do the bidding of the Trump administration while his committee is supposed to be conducting an independent investigation of Russia’s meddling in the last presidential election.

Chairman Nunes has also been faulted by his congressional colleagues for sharing the information with President Trump before consulting with other members of the intelligence committee. The congressman has refused to identify his sources, saying he needed to protect them so others would feel safe coming to the committee with sensitive information. He disclosed the existence of the intelligence reports on March 22, and in his public comments he has described his sources as whistle-blowers trying to expose wrongdoing at great risk to themselves.

Edgar M. Welch, a 28-year-old father of two from Salisbury (NC) recently read online that Comet Ping Pong, a pizza restaurant in northwest Washington, was harboring young children as sex slaves as part of a child-abuse ring led by Hillary Clinton. The articles making those allegations were widespread across the web, appearing on sites including Facebook and Twitter. Apparently concerned, Welch drove about six hours from his home to Comet Ping Pong to see the situation for himself, according to court documents. Not long after arriving at the pizzeria, the police said, he fired from an assault-like AR-15 rifle. The police arrested him. They found a rifle and a handgun in the restaurant. No one was hurt.

Unbeknown to Welch, what he had been reading online were fake news articles about Comet Ping Pong, which have swollen in number over time. The false articles against the pizzeria began appearing on social networks and websites in late October, not long before the presidential election, with the restaurant identified as being the headquarters for a child-trafficking ring. The articles were soon exposed as false by publications including The New York Times, The Washington Post and the fact-checking website Snopes. But the debunking did not squash the conspiracy theories about Comet Ping Pong — instead, it led to the opposite.

FBI Director James Comey told Congress that he had seen no evidence in a recently discovered trove of emails to change his conclusion that Hillary Clinton should face no charges over her handling of classified information.

Comey’s announcement, just two days before the election, was an effort to clear the cloud of suspicion he had publicly placed over her presidential campaign in late October when he alerted Congress that the FBI would examine the emails. “Based on our review, we have not changed our conclusions that we expressed in July with respect to Secretary Clinton,” Director Comey wrote in a letter to the leaders of several congressional committees. He said agents had reviewed all communications to and from Clinton in the new trove from when she was secretary of state.
