Authorities are investigating racist text messages sent to black Americans across the country telling them to report to a plantation "to pick cotton".
Black Americans, including school and college students, were among the recipients in states including Alabama, North Carolina, Virginia, New York and Pennsylvania.
“The FBI is aware of the offensive and racist text messages sent to individuals around the country and is in contact with the Justice Department and other federal authorities on the matter,” the agency said.
The messages appear to have started on Wednesday, the day after election day. Some of the messages mentioned the Trump campaign – which strongly denied any connection.
