Impeachment hearings schedule

Here's a rough schedule of how the week will play, per House staffers involved in the probe:

Tuesday

9 a.m.: Williams, aide to Vice President Mike Pence, and Vindman, director for European Affairs at the National Security Council, will go before the House Intelligence Committee. They will be the first people to testify who were on the July 25 phone call between Trump and Ukrainian President Volodymyr Zelensky.

2:30 p.m.: Ambassador Kurt Volker, former envoy to Ukraine, and Tim Morrison, White House aide with the NSC, will testify before the House Intelligence Committee. Volker and Gordon Sondland, ambassador to the European Union, have previously testified in a closed door meeting with the committee with details supporting Democrats' claim that Trump tried to execute a shadow foreign policy with Ukraine.

Wednesday

9 a.m.: Sondland will testify before the committee. This will be the first time Sondland publicly addresses claims that he was working closely with Trump in dealing with Ukraine and that he'd told the president that the Ukrainians were ready to comply with his demands.

2:30 p.m.: Laura Cooper, deputy assistance secretary of Defense, and David Hale, undersecretary of State, will testify. Cooper previously described to the committee a state of frenzy within the administration after Trump ordered a freeze on military aid to Ukraine.

Thursday

9 a.m.: Fiona Hill, former senior director for Europe and Russia at the NSC, and David Holmes, political counselor at the U.S. Embassy in Kyiv will testify. Hill had previously told House investigators that then-National Security Adviser John Bolton instructed her to report her concerns about Rudy Giuliani and Trump's dealings with Ukraine to NSC lawyers.
