Donald Trump's presidency was rocked when the United States House of Representatives made history by voting to impeach him on two counts: abuse of power and obstruction of Congress. The impeachment inquiry, sparked by a whistleblower's complaint, accused Trump of pressuring Ukraine's president to investigate political rival Joe Biden in exchange for military aid. With a largely party-line vote, the Democratic-led House approved Article I (abuse of power) 230-197 and Article II (obstruction) 229-198, marking Trump as only the third US president to be impeached. This monumental decision sent shockwaves across the nation, setting the stage for a Senate trial in early 2020.
