President Donald Trump questioned the legitimacy of the US midterm election results following sweeping losses for Republicans, just days after telling the press he would accept the outcome.
On election night, Trump told the New York Times he was "absolutely willing" to accept the results, in which Democrats retook both chambers of Congress.
He appeared to reverse course on Truth Social on Monday, asking: "Does anybody really believe that this 'Election' was honest".
State and local officials across the US reported mostly smooth elections this year. Some key races, including US Senate contests in Alaska and Mississippi, have yet to be called.
