Pennsylvania election officials certified Joe Biden as the winner of the commonwealth’s 2020 presidential tally, Gov. Tom Wolf said on Tuesday.

“Today @PAStateDept certified the results of the November 3 election in Pennsylvania for president and vice president of the United States.

As required by federal law, I’ve signed the Certificate of Ascertainment for the slate of electors for Joe Biden and Kamala Harris,” Wolf, a Democrat, said in the posting.

The 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 Harris with 3.46 million votes, Trump and Vice President Mike Pence with 3.38 million, and Libertarian Jo Jorgensen with 79,000.

Secretary of State Kathy Boockvar, in a news release, called the state’s election officials and poll workers “the true heroes of our democracy.”

“We are tremendously grateful to all 67 counties who have been working extremely long hours to ensure that every qualified voter’s vote is counted safely and securely,” Boockvar said.

Trump, who lost the state’s 20 electoral votes to Biden, has made Pennsylvania a centerpiece of his unsuccessful legal attempts to invalidate the election results.

A federal judge on Saturday dealt a serious blow to the Trump campaign’s legal efforts by dismissing a lawsuit he said lacked evidence and offered “strained legal arguments without merit and speculative accusations.”

Pennsylvania and its 20 electoral votes put Biden over the 270 vote threshold to win the White House on Nov. 7.

Meanwhile, the Nevada Supreme Court made Joe Biden’s win in the state official on Tuesday, approving its final canvass of the Nov. 3 election.

The unanimous action by the seven nonpartisan justices sends to Democratic Gov. Steve Sisolak results that will deliver six electoral votes from the western U.S. battleground state to Biden.

The court action drew extra scrutiny amid legal efforts by the state GOP and Trump campaign to prevent sending vote-by-mail ballots to all 1.82 million active registered voters and then to stop the counting of the 1.4 million votes that were cast.

Nevada’s six Democratic presidential electors are scheduled to meet Dec. 14 in the state capital of Carson City.

Biden won by Nevada 33,596 votes, according to results approved by elected officials in Nevada’s 17 counties — including Clark County, which encompasses Las Vegas, and Washoe County, which includes Reno.

Biden has 306 electoral votes to President Trump’s 232.
