• A new fight over the Affordable Care Act broke out on Tuesday, as Democrats denounced the Trump administration for asking a federal appeals court to invalidate it.

• The most enduring legacy of Robert S. Mueller’s investigation may be his decision not to take action on President Trump’s norm-shattering interventions in the law enforcement system. Future presidents may feel entitled to take similar actions.

• As the Trump administration celebrates Mr. Mueller’s finding that the president did not conspire with Russia, a darker theme is emerging: a message that Mr. Trump’s perceived enemies will pay.
