The Oregon Department of Motor Vehicles is investigating the alleged incident.
An Oregon DMV employee has been placed on leave pending an investigation after allegedly posting anti-immigrant Facebook comments including "I personally think they should shoot them all at the border," authorities said.
Lori McAllen's alleged comments and account have since been taken down, but screenshots of the posts have been widely shared online and the state Department of Motor Vehicles issued a statement after receiving scores of complaints.
"There is an active investigation into the matter," the statement said. "Thank you to those who have shared your concerns and we take this matter seriously."
The alleged comments drew heavy criticism on social media, where the screenshots went viral.
"We received thousands of posts online and probably more than 100 phone calls," Oregon Department of Transportation spokesman Dave Thompson told CBS News. "The social media posts were coming in fast and furious. It went viral."
McAllen has not publicly commented on the events.
