1. The second day of impeachment hearings ramped up the drama as the former ambassador to Ukraine painted a striking account of her ouster and offered a damning indictment of foreign policy in the Trump era.

Marie Yovanovitch told impeachment investigators she was “shocked, appalled, devastated” that President Trump insulted her in a call with another foreign leader. She described how she had been the target of a smear campaign orchestrated by Rudolph Giuliani, Mr. Trump’s personal lawyer, that would push her out of her job.

Mr. Trump reinforced Ms. Yovanovitch’s narrative by attacking her on Twitter at the very moment she was testifying about his veiled threat that she would “go through some things.”
