HARRISBURG, Pa. - President Donald Trump’s campaign launched a lawsuit to stop the certification of the election results in Pennsylvania, suing Monday as counties continued to sort through provisional ballots and late-arriving mail-in ballots nearly a week after the election.The Associated Press on Saturday called the presidential contest for former Vice President Joe Biden, after determining that the remaining ballots left to be counted in Pennsylvania would not allow Trump to catch up.But Trump’s campaign filed litigation in federal court over Pennsylvania’s presidential election, and Trump has refused to concede.“The election is not over,” Trump’s general counsel, Matthew Morgan, said in a news conference in Washington,.
