WASHINGTON - U.S. President Donald Trump's campaign on Monday filed a lawsuit in a Pennsylvania federal court, seeking to block state officials from certifying President-elect Joe Biden's victory in the state. 

The lawsuit, brought by the campaign and two registered voters, alleged Pennsylvania's mail-in voting system "lacked all of the hallmarks of transparency and verifiability that were present for in-person voters." 

The lawsuit claims Pennsylvania officials violated the U.S. Constitution by creating "an illegal two-tiered voting system" where voting in-person was subject to more oversight than voting by mail. 

It was filed against Pennsylvania Secretary of State Kathy Boockvar and the boards of elections in Democratic-leaning counties that include Philadelphia and Pittsburgh. Boockvar's office did not immediately respond to a request for comment.

The president, who has spent months trying to undermine the election with unproven allegations of fraud, has pledged to go forward with a legal strategy that he hopes will overturn state results that gave Biden the win in Tuesday’s vote. 

The Trump campaign and Republicans have brought numerous lawsuits since Election Day over alleged election irregularities. Judges have already tossed cases in Georgia and Michigan. 

Separately, some Republican state legislators in Pennsylvania on Monday said in a press release that they would "call for a legislative-led audit of the 2020 election and demand election results not be certified, nor electors be seated, until the audit is complete." 

In the United States, a candidate becomes president by securing the most “electoral” votes rather than winning a majority of the national popular vote. Electors generally cast their vote for the winner of the popular vote in their respective states. They are slated to meet on December 14. 

Edward Foley, who specializes in election law at the Moritz College of Law at the Ohio State University, said the Pennsylvania legislature couldn't stop the certification of the vote without changing the law. 

“To do that, they would have to attempt to amend the state statute and that is going to be vetoed” by Pennsylvania's Democratic governor, Foley said. 

The Pennsylvania case was assigned to U.S. District Judge Matthew Brann, an appointee of former President Barack Obama. 

What Happens Next?

What It Means to Become President-Elect in the US

In the United States, Democrat Joe Biden is being called the president-elect.

President-elect is a descriptive term not an official office. As such, Biden has no power in the government, and he would not until he is inaugurated at noon on January 20, 2021.

American news networks, which track all of the vote counting, determined on November 7 that Biden’s lead had become insurmountable in Pennsylvania, putting him over the 270 electoral votes needed to be president. Within minutes of determining his lead was mathematically assured, they projected him as the winner.

That is why news organizations, including VOA, are calling Biden the "projected winner."

Sometimes, in the case of particularly close elections, when news networks make this call, the other candidate does not concede victory. President Donald Trump has not done so, alleging voter fraud without substantial evidence and vowing to fight on. The president’s position has left Washington lawmakers divided, with Republicans backing a legal inquiry into allegations of vote fraud, even as they celebrate other congressional lawmakers who won their races.

When will the dispute be resolved?

The U.S. election won’t be officially certified for weeks. In the meantime, court challenges and state recounts could occur.

So far, the Trump administration has not provided evidence for any fraud that could overturn the result, but there is still time for more legal challenges.

Once states have certified the vote, pledged electors then cast their votes in the Electoral College in mid-December. Congress then certifies the overall Electoral College result in early January, about two weeks before Inauguration Day.
