US President Donald Trump alleged on Wednesday that there had been "surprise ballot dumps" in states where he had been leading Democrat Joe Biden in the race for the White House.
"Last night I was leading, often solidly, in many key States, in almost all instances Democrat run & controlled," Trump tweeted. "Then, one by one, they started to magically disappear as surprise ballot dumps were counted."
Trump did not offer any evidence for his allegation of "ballot dumps" and there have been no reports of any irregularities.
The leads in numerous states have shifted back-and-forth between the candidates as votes are counted.

Joe Biden vowed Wednesday that his campaign would not "rest until every vote is counted" in the US election after President Donald Trump sought Supreme Court intervention to halt the counting process.
"We won't rest until everyone's vote is counted," Trump's Democrat rival Biden said on Twitter.
