Trump campaign sues Pennsylvania over vote-by-mail

The Trump campaign filed a federal lawsuit Monday in Pennsylvania, saying it’s fighting for election security by opposing the state’s move on mail-in-voting ahead of November’s election.

“Free and fair elections are essential to the right of Americans to choose through their vote whom they elect to represent them,” the campaign’s lawsuit read. “Upending our entire election process and undermining ballot security through unmonitored by-mail voting is the single greatest threat to free and fair elections. To be free and fair, elections must be transparent and verifiable.”

The filing comes after Pennsylvania officials made changes to the state’s absentee voting system.
