Recent tallies have shown Democrat Hillary Clinton winning the national popular vote by more than 2 million, even as Trump won the Electoral College that picks the next president.

Thomsen called Trump’s remarks “an insult to the people that run our elections.”

“I’ve never seen this kind of attack on poll workers, and on how this system works,” Thomsen said.

The Clinton campaign has signaled it will closely monitor the recount in Wisconsin and potential recounts in Michigan and Pennsylvania. The campaign’s attorney, Marc Elias, wrote that it has examined the possibility of attempts to hack election results but has “not uncovered any actionable evidence.”

Majority are paper ballots

About 90 percent of all ballots cast in Wisconsin are paper ballots, the vast majority of which are tabulated by optical scanners, with the remainder counted by hand, according to Elections Commission spokesman Reid Magney. About 10 percent of votes are cast on touch-screen machines.

A recount of the paper ballots will involve counting them by machine or hand, a decision that will be left to each of the state’s 72 counties. Dane County Clerk Scott McDonell said Monday on Twitter the county would conduct a hand recount.
