Edward Snowden, the NSA whistleblower, announced a new app he helped create, called Haven, that will let users essentially spy on spies, per AP.

Haven "aims to protect laptops from physical tampering" and Snowden says "it's an open-source tool designed for human rights activists and other people at risk and it uses an Android phone's sensors to detect changes in a room," AP reports.

Ohio Gov. Mike DeWine (R) has tested positive for COVID-19 and plans to quarantine at his home for the next 14 days, his office announced Thursday. He currently has no symptoms.

Why it matters: The 73-year-old DeWine was set to meet President Trump Thursday on the tarmac at an airport in Cleveland and was tested as part of standard protocol. He is the second governor known to have contracted the coronavirus, after Oklahoma Gov. Kevin Stitt (R).

The extremely rich tend to think very highly of themselves, and of their ability to bend the world to their will. So when they start giving their money away, they tend to retain maximum control.

She pledged to give away substantially all of that money after she gained autonomy over her own wealth. Judging by her first 116 grants, she's doing so in a refreshingly radical — and humble — manner.

President Trump's Iran envoy, Brian Hook, is stepping down, Secretary of State Mike Pompeo confirmed Thursday. He will be replaced with Venezuela envoy Elliott Abrams, a noted Iran hawk who will serve in both roles.

Why it matters: Hook had been tasked with executing Trump's "maximum pressure" policy toward Iran, working closely with Pompeo. That strategy has deepened tensions and thus far failed to force Iran back to the negotiating table, as Trump had hoped.
