 President Donald Trump’s re-election campaign, the national Republican Party and four Pennsylvania members of Congress sued Monday to force changes to how the state collects and counts mail-in ballots under revamped rules.

The federal lawsuit filed in Pittsburgh claims that as voters jumped to make use of the greatly broadened eligibility for mail-in ballots during the June 2 primary, practices and procedures by elections officials ran afoul of state law and the state and federal constitutions.

It claims the defendants, which are the 67 county election boards and Secretary of State Kathy Boockvar, “have inexplicably chosen a path that jeopardizes election security and will lead — and has already led — to the disenfranchisement of voters, questions about the accuracy of election results, and ultimately chaos” ahead of the Nov. 3 general election.

A spokeswoman for Boockvar, a Democrat, declined comment about the litigation, as did the head of the County Commissioners Association of Pennsylvania, whose members administer elections.

The head of the Pennsylvania Democratic Party called the lawsuit an effort to suppress votes as a campaign tactic, noting Democrats far outpaced Republicans in getting their voters to apply for mail-in ballots ahead of the primary.

“Statewide vote-by-mail was a bipartisan proposal passed by Republican majorities in Harrisburg,” said Sinceré Harris, the state Democrats’ executive director.
