Democratic Sen. Richard Blumenthal today asked Twitter, Google and Facebook to inform all of their users who were exposed to ads and content purchased or placed by Russian actors during the 2016 election.

"You owe your users full information regarding when, where, and how they may have been unwitting participants in Russia's campaign to sow division and spread disinformation in the United States," Blumenthal wrote in letters to the companies' CEOs.

Context: The companies took a lot of heat on Capitol Hill last week for allowing Russian content with malicious intent to spread on their platforms and are under pressure to add new safeguards. Several lawmakers called on the companies to release more information about the ads and stories that appeared on their platforms so citizens have a better idea of what it looks like. Some ads have been released.

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.

Trump considering order on pre-existing condition protections, which already exist

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.
