'US election rigging exposed'

Hillary Clinton is being urged by expert computer scientists and election lawyers to call for a recount in three swing states won by Trump, publication New York has reported.

Persuasive evidence has reportedly been found that shows results in Wisconsin, Michigan, and Pennsylvania may have been manipulated or hacked.

The group, which includes voting-rights attorney John Bonifaz and J. Alex Halderman, the director of the University of Michigan Center for Computer Security and Society, is lobbying Clinton's team privately before going on the record about their findings.

Their findings apparently show a trend of Clinton performing worse in counties that relied on electronic voting machines compared to paper ballots and optical scanners.

 Based on this statistical analysis, Clinton may have been denied as many as 30 000 votes. She lost Wisconsin by 27 000.

The vote in Michigan has still not been called as the results were too close - and the 16 electoral votes in the state have not been given to Trump or Clinton.

Clinton would need to win Michigan and overturn the results in Wisconsin and Pennsylvania to win the electoral college.

Time is of the essence if Clinton is to pursue challenging the results.  The deadline in Wisconsin to file for a recount is Friday; in Pennsylvania, it's Monday; and Michigan is next Wednesday.

Both Trump and Clinton have declined to respond to questions regarding the report, CNN says.
