President Donald Trump will push ahead on Tuesday with legal challenges to the results of last weeks election after US attorney general William Barr told federal prosecutors to look into any substantial allegations of voting irregularities.
Mr Barrs directive to prosecutors prompted the top lawyer overseeing voter fraud investigations to resign in protest.
It came after days of attacks on the integrity of the election by Mr Trump and Republican allies, who have alleged widespread voter fraud, without providing evidence.
Mr Trump has not conceded the election to Democrat Joe Biden, who on Saturday secured more than the 270 votes in the Electoral College needed to win the presidency.
The Trump campaign has filed several lawsuits claiming the election results were flawed. Judges have tossed out lawsuits in Michigan and Georgia, and experts say Mr Trumps legal efforts have little chance of changing the election result.
Mr Barr told prosecutors on Monday that fanciful or far-fetched claims should not be a basis for investigation and his letter did not indicate the Justice Department had uncovered voting irregularities affecting the outcome of the election.
But he did say he was authorising prosecutors to pursue substantial allegations of irregularities of voting and the counting of ballots.
Richard Pilger, who for years has served as director of the Election Crimes Branch, announced in an internal email he was resigning from his post after he read the new policy and its ramifications.
Mr Bidens campaign said Mr Barr was fuelling Trumps far-fetched allegations of fraud.
Those are the very kind of claims that the president and his lawyers are making unsuccessfully every day, as their lawsuits are laughed out of one court after another, said Bob Bauer, a senior adviser to Mr Biden.
Earlier on Monday, Mr Trumps campaign filed a lawsuit to block Pennsylvania officials from certifying Mr Bidens victory in the battleground state.
It alleged the states mail-in voting system violated the US 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. Boockvars office did not immediately respond to a request for comment.
Jessica Levinson, a professor at Loyola Law School in Los Angeles, said the latest lawsuit in Pennsylvania was unlikely to succeed and reads like a rehash of many of the arguments the Trump legal team has made in and outside the courtroom.
Mr Trumps re-election team asked for patience on Monday to pursue allegations of voter fraud.
This election is not over, far from it, Kayleigh McEnany, the White House press secretary, told reporters at a briefing in what she said was her capacity as a Trump campaign adviser.
Mr Trump and Republicans have repeatedly tried to do away with the 2010 law passed under former president Barack Obama, when Mr Biden was his vice president.
The Supreme Court fended off previous challenges in 2012 and 2015. The Court now has a 6-3 conservative majority after Mr Trumps third appointee, Amy Coney Barrett, was confirmed last month.
As Mr Biden begins work on his transition, his team is considering legal action over a federal agencys delay in recognising his victory over Trump.
The General Services Administration (GSA) normally recognizes a presidential candidate when it becomes clear who has won so a transition of power can begin.
But that has not yet happened and the law does not spell out when the GSA must act. GSA Administrator Emily Murphy, appointed by Mr Trump in 2017, has not yet determined that a winner is clear, a spokeswoman said.
A Biden transition official told reporters it was time for the GSAs administration to grant what is known as an ascertainment recognizing the president-elect, and said the transition team would consider legal action if it was not granted.
Legal action is certainly a possibility, but there are other options as well that were considering, said the official, who spoke on condition of anonymity, declining to outline other options. – Reuters
