Chicago and Illinois' Cook County are suing Uber over the 2016 data breach that implicated 57 million driver and passenger accounts and the company's decision not to publicly disclose it until this month, per the Chicago Sun-Times. The paper notes that the city's mayor, Rahm Emanuel, is the brother of an Uber investor and is seen as having been favorable to the ride-hailing company in the past.

Why it matters: State, local and federal officials aren't happy about the breach, with attorneys general around the country investigating the issue and members of Congress writing to the company about the hack on Monday.

What they're saying: "We take this matter very seriously and we are happy to answer any questions regulators may have," said an Uber spokesperson in a statement.

Watch for President Trump to address Joe Biden as “the big guy” or “the chairman” at tonight's debate as a way of dramatizing the Hunter Biden emails. Hunter's former business partner Tony Bobulinski is expected to be a Trump debate guest.

The big picture: Trump's advisers universally view the first debate as a catastrophe — evidenced by a sharp plunge in Trump’s public and (more convincingly for them) private polling immediately following the debate.

Energetic Bear, a Russian state-sponsored hacking group, has stolen data from two servers after targeting state and federal government networks in the U.S. since at least September, the FBI and Cybersecurity and Infrastructure Security Agency said on Thursday.

Driving the news: Director of National Intelligence John Ratcliffe announced Wednesday that Iran and Russia had obtained voter registration information that could be used to undermine confidence in the U.S. election system.
