Robots that double as security guards are growing as a presence in cities across the U.S., per McClatchy DC. The bots, equipped with laser scanning, 360-degree video, and thermal imaging are self-sufficient, cheaper than human beings, can work 24-hour days, and require no benefits.

Yes, but: Letting the bots loose on the streets can be dangerous, and some manufacturers are still working out how to ensure the robots don't hurt pedestrians in their path. Meanwhile, no mechanism to hold the robots, or their human operators, accountable has been established yet. "If you have a robot with no distinguishing marks, who are you going to call?" A. Michael Froomkin, a University of Miami Law School professor, told McClatchy.

Sen. Elizabeth Warren and Hillary Clinton both are slated to speak on the Wednesday of the Democratic convention — Aug. 19 — four sources familiar with the planning told Axios.

Why it matters: That's the same night Joe Biden's running mate (to be revealed next week) will address the nation. Clinton and Warren represent two of the most influential wise-women of Democratic politics with the potential to turn out millions of establishment and progressive voters in November.

President Trump announced on Friday he will pursue an executive order requiring insurance companies to cover pre-existing conditions, something that is already law.

Why it matters: The Affordable Care Act already requires insurers to cover pre-existing conditions. The Trump administration is currently arguing in a case before the Supreme Court to strike down that very law — including its pre-existing condition protections.
