PORTLAND, Ore. (AP) — A Clackamas, Oregon, man has pleaded guilty to placing calls to airports in Nevada and Texas, reporting his father and brother as terrorists because they got an invitation to a family wedding and he didn't.

The Oregonian/OregonLive reports 38-year-old Sonny Donnie Smith admitted to placing anonymous phone calls to security offices at McCarran International Airport in Las Vegas and the Midland International Air and Space Port in Midland, Texas.

Assistant U.S. Attorney Hannah Horsley says the calls were made Sept. 3, 2016.

The calls prompted an FBI investigation that revealed no terrorist threats. Smith's father and brother were detained and questioned by investigators, and the brother missed his flight.

Smith faces up to two years in prison, a $250,000 fine and one year of supervised release at sentencing set for May.
