Crazy story via Electionline:

FBI agents questioned state and county election officials and state political party leaders about two international election observers who toured Nebraska before November’s general election.

In at least two interviews, federal law enforcement agents asked if the veteran observers from the Organization for Security and Co-operation in Europe — one from Russia, the other from Switzerland — offered a pen as a gift.

According to multiple people who described the schematic shown to them by FBI agents, the pen may have doubled as a covert listening device, but those who spoke to law enforcement said they were not offered any object.
