2016 United States presidential election recounts: Following Republican nominee Donald Trump's presumed electoral college victory in the United States presidential election of 2016, a group of computer scientists, cyber security experts, and election monitors raised concerns about the integrity of the election results.  They urged the campaign staff of Democratic nominee Hillary Clinton, who had conceded the campaign on November 9, to petition for a recount in three key states: Michigan, Pennsylvania, and Wisconsin.  When the Clinton campaign declined to file for recounts, Green Party presidential nominee Jill Stein agreed to spearhead the recount effort on November 23, on the grounds that unspecified "anomalies" may have affected the election's outcome.  The Clinton team subsequently pledged to support the recount efforts "in order to ensure the process proceeds in a manner that is fair to all sides."  President-elect Trump and his supporters filed legal motions in all three states to prevent the recounts.  Two other states were the subject of recount bids that were separate from Stein's efforts in the Rust Belt states: American Delta Party/Reform Party presidential candidate Rocky De La Fuente filed for a partial recount in Nevada on November 30, and three Florida citizens filed for a complete hand recount in their state on December 6.
