The Fort Bend County Sheriff's Office in Texas reported it had taken an individual into custody for "attempting to vote a second time" during the Nov. 8 presidential elections.
According to the FBCSO's Twitter, the person detained "claimed he worked for [Republican presidential nominee Donald Trump] and was testing the system."
ABC13 identified the man as 62-year-old Phillip Cook of Richmond, Texas.
While Trump has long been sounding the alarm on what he's called an imminent conspiracy to rig the elections, typically his implication has been that Democrats are the ones doing the rigging.
The FBCSO did not immediately respond to a request for comment.
