The petition seeks to reverse a trio of Pennsylvania Supreme Court cases having to do with mail-in ballots.

U.S. Middle District Judge Matthew Brann in turned down the request for an injunction by Trump's campaign, spoiling the incumbent's hopes of somehow overturning the results of the presidential contest.

The new court filing argues the state's Republican-controlled legislature should select the electors that will cast votes in the U.S. Electoral College system.

In his first argument in federal court since 1992, Giuliani pushed false allegations on behalf of the Trump campaign that Democrats nationwide had conspired to steal the election.

The Trump campaign wants to prevent certification of results that give President-elect Joe Biden the state's 20 electoral votes, suing over election procedures that were not uniform across the state.

Trump's campaign dropped the allegation that hundreds of thousands of mail-in and absentee ballots were illegally processed without its representatives watching.

The divisive and bitterly contested campaign came to an end four days after election night.

In yet another battleground state, it's still too early to call.

The Democrat candidate claimed a congressional election in a Republican heartland in Pennsylvania, as a vote seen as a referendum on Donald Trump's performance as president remained officially too close to call early on Wednesday.
