Report of Evidence in the Democrats' Impeachment Inquiry in the House of Representatives [open pdf - 2MB]
From the Executive Summary: "The sum and substance of the Democrats' case for impeachment is that President Trump abused his authority to pressure Ukraine to investigate former Vice President Joe Biden, President Trump's potential political rival, for President Trump's benefit in the 2020 election. Democrats say this pressure campaign encompassed leveraging a White House meeting and the release of U.S. security assistance to force the Ukrainian President to succumb to President Trump's political wishes. Democrats say that Mayor Rudy Giuliani, the President's personal attorney, and a 'shadow' group of U.S. officials conspired to benefit the President politically. [...] The evidence does not support the accusation that President Trump pressured President Zelensky to initiate investigations for the purpose of benefiting the President in the 2020 election. The evidence does not support the accusation that President Trump covered up the summary of his phone conversation with President Zelensky. The evidence does not support the accusation that President Trump obstructed the Democrats' impeachment inquiry."
