HARRISBURG — Gov. Tom Wolf’s administration is settling a vote-counting lawsuit stemming from the 2016 election, in part by affirming a commitment it made previously to push counties to buy voting systems that leave a verifiable paper trail by 2020.

Paperwork filed Thursday in Philadelphia caps a lawsuit that Green Party presidential candidate Jill Stein filed in 2016 seeking recounts in Wisconsin, Pennsylvania and Michigan.

All three states had a history of backing Democrats for president before they were unexpectedly won by Republican Donald Trump.
