Stein announced Nov. 23 that she would start raising money to fund the recounts, after computer scientists suggested that ballot machines could have been hacked. She raised more than $6 million in donations to pay for filing and legal fees, approaching her goal of $7 million. That goal was later revised up to $9.5 million.

Recount requests have been filed in Michigan and Wisconsin, amid litigation by local Republicans and Donald Trump. The president-elect, who won by narrow margins in all three states, has described the recount initiative as a “scam.”

Abandoning the recount in Pennsylvania means giving up on any slim hope of revising the Nov. 8 presidential election in favor of Hillary Clinton. Although the Democratic candidate leads the popular vote by 2.5 million, Clinton would have had to win recounts in all three states in order to overturn Trump’s lead in the electoral college.
