First Impeachment: Abuse of Power and Obstruction of Congress Over Ukraine Pressure Campaign
Tier 2Acquitted by Senate2019-07-25 to 2020-02-05
Factual Summary
On December 18, 2019, the United States House of Representatives impeached President Donald J. Trump on two articles: abuse of power and obstruction of Congress. Both charges arose from Trump's efforts to pressure Ukraine to announce investigations into his political rival, former Vice President Joe Biden, while withholding approximately $391 million in congressionally approved military aid as leverage.
On July 25, 2019, Trump spoke by phone with Ukrainian President Volodymyr Zelensky. During the call, Trump asked Zelensky to investigate Biden and his son Hunter Biden in connection with Hunter's former position on the board of Ukrainian energy company Burisma. Trump also asked Zelensky to coordinate with his personal attorney, Rudy Giuliani, and with Attorney General William Barr. The White House later released a memorandum of the call confirming the key exchanges but described it as a record rather than a verbatim transcript.
On August 12, 2019, a CIA officer detailed to the White House filed a formal whistleblower complaint with the Intelligence Community Inspector General, who found the complaint credible and urgent. Speaker Nancy Pelosi announced a formal impeachment inquiry on September 24, 2019. The House Intelligence Committee conducted depositions and public hearings through October and November 2019.
Article I (Abuse of Power) passed 230 to 197. Article II (Obstruction of Congress) passed 229 to 198. No Republican voted in favor of either article.
The Senate trial began on January 16, 2020, with Chief Justice John Roberts presiding. On January 31, the Senate voted 51 to 49 against subpoenaing additional witnesses. On February 5, 2020, the Senate voted to acquit on both articles. On Article I, the vote was 48 to 52 for acquittal. Senator Mitt Romney of Utah voted to convict, becoming the first senator in history to vote to remove a president of his own party. On Article II, the vote was 47 to 53 for acquittal. A two-thirds supermajority of 67 votes was required for conviction.

Counterarguments and Context
Trump and his legal team consistently denied wrongdoing. They argued the phone call was "perfect" and contained no improper quid pro quo, citing the White House memorandum as exonerating. They noted that Ukraine received the military aid and a White House meeting occurred without Ukraine announcing any investigations, undermining the claim that a coercive exchange had been completed. Trump's attorneys argued the articles of impeachment did not meet the constitutional threshold of "Treason, Bribery, or other high Crimes and Misdemeanors" and that the inquiry was procedurally defective and driven by partisan animus. On the obstruction charge, they argued the refusal to comply with House subpoenas was grounded in executive privilege and that the House should have sought court enforcement.
Author's Note
This entry is classified as Tier 2 because the impeachment constitutes a formal constitutional proceeding with recorded votes but did not result in conviction or removal. The Senate acquittal is not a judicial finding of innocence; it reflects that the prosecution did not achieve the constitutionally required two-thirds supermajority.
