The US President Donald Trump’s campaign team has filed a lawsuit against the vote counting for alleged electoral irregularities in the federal court in Pennsylvania. The reason given in the complaint is that the postal voting system in Pennsylvania “does not have the necessary transparency and verifiability” that apply to voting in polling stations. Voters would have had different yardsticks “just based on how they cast their vote, and we believe this two-tier electoral system resulted in potentially fraudulent votes being counted without proper verification or control,” said Matt Morgan, attorney for the Trump campaign. An injunction is to prevent challenger Joe Biden from being declared the winner in the US state.
