Nancy Pelosi’s evolution on impeachment

Having said nine months ago that she opposed the “divisive” idea of impeaching President Trump, the speaker has announced a timetable that could lead to a vote in the House before Christmas.

She was swayed, our congressional correspondent writes, by the news of Mr. Trump’s pressure on Ukraine to investigate his political rivals. Her shift was “in part the story of her sense of timing, her methodical approach to decision making and her ability to read the sensibilities and political needs of her fractious and often unruly caucus.”

After her address on Thursday, Ms. Pelosi warned a reporter who asked whether she hated Mr. Trump: “Don’t mess with me.”

What’s next: The White House faces a deadline today to notify the House Judiciary Committee whether it intends to present a defense or put forward witnesses. The panel has scheduled its next impeachment hearing for Monday.
