The EPA's internal watchdog is opening a probe into how the agency wrote controversial rules that weakened Obama-era carbon emissions standards for cars and light trucks.

Why it matters: The Obama-era emissions and mileage standards that extended into the mid-2020s were a pillar of the former president's climate change agenda.

  • The Trump administration's rewrite has been among the most sprawling and bitter regulatory fights in recent years, and has led to splits within the auto industry, too.
  • The inspector general said the office will explore whether the rules met transparency and record-keeping requirements and "followed the EPA’s process for developing final regulatory actions."
  • The new probe opens another front in the ongoing legal and political tussles over the standards.

The big picture: The prior rules would have required roughly 5% annual efficiency improvements, while the rewritten standards finalized this year mandate 1.5% year-over-year gains.

  • Trump officials called the Obama standards unwieldy and said the rewritten rules will cut traffic deaths — a conclusion that critics contest.

The intrigue: The ultimate shape of U.S. auto rules will be in flux for a while. The new standards are being litigated, and if Joe Biden wins, he'd look to revive more stringent requirements and extend them.

Trump pushes back on changes to upcoming presidential debates

President Trump suggested Thursday that he'll resist any moves that could cut off candidates' microphones in the next debate if he continues to talk over his opponent and the moderator.

  • "Why would I allow the Debate Commission to change the rules for the second and third Debates when I easily won last time?" he tweeted.

The big picture: White House and campaign officials insist Trump is still committed to two remaining debates, despite the fallout from Tuesday, including poor reviews and discussions of new guardrails.

Sen. Kamala Harris appealed to Black voters in Georgia on Friday, urging them to "honor the ancestors" by casting ballots, and again calling President Trump a "racist."

Why it matters: The U.S. saw a significant decline in African-American voter turnout between 2012 and 2016, reaching its lowest point since 2000. Higher turnout among Black Americans this year could tip the balance in favor of Democrats in key battleground states, including Georgia.
