Keith Block is stepping down as co-CEO of Salesforce, leaving co-founder Marc Benioff as the sole chief executive of the company once again.

The big picture: Block, who joined the company in 2013 from Oracle, was promoted to co-CEO less than two years ago to give Benioff more time to focus on other interests. Block will stay on as an adviser to Benioff, the company said.

Meanwhile: Salesforce separately agreed Tuesday to buy Vlocity, which makes cloud-based apps that run on Salesforce's signature platform, for $1.33 billion.

Sen. Jim Inhofe (R-Okla.), chair of the Senate Armed Services Committee, told reporters Wednesday that he plans to move ahead with a crucial defense-spending bill without provisions that would eliminate tech industry protections, defying a veto threat from President Trump.

Why it matters: Inhofe's public rebuke signals that the Senate could have enough Republican backing to override a potential veto from Trump, who has demanded that the $740 billion National Defense Authorization Act repeal Section 230 of the Communications Decency Act.

Uber is in advanced talks to sell its Uber Elevate unit to Joby Aviation, Axios has learned from multiple sources. A deal could be announced later this month.

Between the lines: Uber Elevate was formed to develop a network of self-driving air taxis, but to date has been most notable for its annual conference devoted to the nascent industry.

Setting the Biden-era cybersecurity agenda

The Biden administration will face a wide array of cybersecurity challenges but can take meaningful action in at least five key areas, concludes a new report by the Aspen Cybersecurity Group.

Why it matters: Cybersecurity policy is a rare refuge from Washington's hyperpartisan dysfunction, as shown by the recent work of the bipartisan Cyberspace Solarium Commission. President-elect Joe Biden should have a real opportunity to make progress on shoring up the nation's cybersecurity and cyber capabilities without bumping up against a likely Republican-controlled Senate.
