Trump campaign sues Philadelphia election officials, seeks Republican oversight of ballot counting

US President Donald Trump's campaign on Thursday sued Philadelphia County's Board of Elections, seeking an emergency injunction barring it from counting ballots so long as Republican observers are not present as it said was required under Pennsylvania law.

Trump's campaign said election officials are "intentionally refusing to allow any representatives and poll watchers for President Trump and the Republican Party." The lawsuit was filed with the federal court in Philadelphia.
