It's been nearly one month since Speaker Nancy Pelosi announced a formal impeachment inquiry on Sept. 24.
Why it matters: It's remarkable how fast it has gotten off the ground. You can see how quickly the Ukraine phone call came out of nowhere to become the all-consuming impeachment topic — way faster than the impeachment inquiries into Richard Nixon and Bill Clinton.
The House will vote on a resolution Thursday that will formalize procedures for the next phase of the impeachment inquiry into President Trump, Speaker Nancy Pelosi confirmed on Monday.
Why it matters: Trump and his allies have argued that the current impeachment inquiry is unconstitutional because it hasn't been voted on by the full House — a claim that Pelosi and Democratic leaders have called baseless. However, in a letter to House Democrats Monday, Pelosi wrote that members will vote in order to "eliminate any doubt as to whether the Trump Administration may withhold documents, prevent witness testimony, disregard duly authorized subpoenas, or continue obstructing the House of Representatives."
House Speaker Nancy Pelosi told Bloomberg on Friday that she expects the impeachment inquiry's public hearings to start this month, but she said the House has no deadline to conduct its probe.
The big picture: Pelosi said it's possible the inquiry could stretch into 2020, depending on the details that emerge, according to Bloomberg. She also said the committees conducting the inquiry could continue with closed-door hearings, so long as they're "productive."
