Gov. Gretchen Whitmer declared a state of emergency in a Michigan county after two dams failed following what one official described as "catastrophic" flooding from heavy rain on Tuesday night.

Details: Whitmer said in a statement the Edenville and Sanford dams in Midland County breached. "In the next 12–15 hours, downtown Midland could be under approximately 9 feet of water," Whitmer told a news conference late Tuesday. Authorities told a news briefing they were evacuating some 10,000 people.

  • "We are anticipating a historic high water level," said City of Midland manager Brad Kaye. He told the briefing late Tuesday what was unfolding was "catastrophic" and "equivalent of a 500-year flood."
  • The National Weather Service tweeted that a Flash Flood Emergency was in place in Midland County until 7:30am Wednesday.

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.
