Pennsylvania Gov. Tom Wolf and Secretary of State Kathy Boockvar thanked the “dedicated” election workers for counting the votes while “under constant attack” for doing so.
The U.S. State Department said Wolf’s “certificate of ascertainment” has been sent to the national archivist in Washington. Pennsylvania’s electors — a mix of elected Democrats, party activists and other staunch Biden backers — will meet in the state Capitol on Dec. 14.
The results show Biden and Vice President-elect Kamala Harris with 3.46 million votes, President Donald Trump and Vice President Mike Pence with 3.38 million, and Libertarian Jo Jorgensen with 79,000.
The Trump campaign filed several unsuccessful lawsuits since the day after the election, alleging unsubstantiated claims of fraud and discrimination against Republican poll watchers in Philadelphia.
Over the weekend, the Pennsylvania Supreme Court rejected the Trump campaign’s efforts to toss out thousands of votes cast in Philadelphia and Allegheny counties. The court ruled there was no fraud or irregularities.
