What to expect on day 3 of opening arguments in Trump's impeachment trial

Schiff, the chairman of the House Intelligence Committee, gave a broad overview of the timeline of the president's pressure campaign in Ukraine.

It centers around a July 25 phone call Trump had with Zelensky, during which he repeatedly pressed Zelensky to launch investigations targeting former Vice President Joe Biden and his son, Hunter, over the latter's employment on the board of the Ukrainian natural-gas company Burisma Holdings.

Trump also asked Zelensky to look into a discredited conspiracy theory started by Russia suggesting Ukraine interfered in the 2016 US election.

But Schiff and the six other impeachment managers detailed that the phone call was just one data point in what turned out to be a months-long effort by Trump and his allies to leverage US foreign policy to bully Ukraine into acceding to the president's personal, political demands.
