Jonathan Paton dropped a lawsuit that sought to have one of his Republican contenders in the 1st Congressional District race removed from the ballot.
Paton had alleged that more than half of Gaither Martin’s signatures were fraudulently collected or gathered under a petition that listed the wrong address.
He withdrew the lawsuit Monday after Martin agreed to throw out 195 signatures that he did not personally witness.
Martin spokesman Nathan Sproul says the campaign determined those signatures weren’t necessary to remain in the race. He called the lawsuit filed less than a week ago frivolous.
Paton and Martin are among four Republicans seeking to represent a large swath of northern and eastern Arizona.
The primary election is Aug. 28.
