The most important week so far of the impeachment inquiry is here.
Democrats will take their case to the American people that President Trump should be impeached, and they'll do it by introducing public testimony from career State Department employees, who will testify under oath to things they've already talked about in private.
Here's what you need to know:
Still no word from the whistleblower: Democrats say they won't present a testimony from the whistleblower whose alarm uncovered Trump's effort to use tax dollars and foreign aid as ransom for his own political benefit.
What the Democrats are saying: The head impeachment inquisitor, House Intelligence Chairman Adam Schiff, argued Saturday that the whistleblower's complaint has been corroborated, which makes testimony from the whistleblower "redundant."
What the GOP is saying: Republicans are focused on arguing that former Vice President Joe Biden and his son, Hunter, should be called to testify — something Democrats will not allow since it would divert focus on Trump's pressure on Ukraine back on the Bidens. Republicans also argued over the weekend that without the whistleblower, the case against the President falls apart.
The White House could release the transcript of an April call between Trump and Ukrainian President Volodymyr Zelensky.
Wednesday: Public testimony is scheduled from Bill Taylor, still the top State Department official in Ukraine, who raised concerns about the shadow foreign policy being pursued by Rudy Giuliani and who internally called out Trump's political appointee for tying political investigations to security aid. Taylor can talk about why Ukraine needs that aid.
Also Wednesday: There will be open testimony from George Kent, who will talk about Giuliani's efforts to get former US Ambassador to Ukraine Marie Yovanovitch removed from her post.
Friday: former US Ambassador to Ukraine Marie Yovanovitch will testify publicly about her recall at Trump's request.
