Willamette (Ore.) Week reported an elections worker is alleged to have filled in blanks on ballots returned to the county for the Nov. 6 election. Citing sources familiar with the matter, the publication said the elections worker -- whose name wasn't reported -- filled in ballots for a straight Republican ticket in races in which voters left their ballots blank.
Under Oregon law marking someone else's ballot is a Class C felony, the report said.
"We are investigating felony violations of Oregon election laws which allegedly took place in Clackamas County and involved a temporary county elections' employee's tampering with cast ballots," Oregon Department of Justice spokesman Jeff Manning told Willamette Week.
Clackamas County Clerk Sherry Hall was unavailable for comment and a spokesman for the county had no comment, the publication said.
