A Donald Trump rally on Friday was postponed after the president called off a rally in Iowa after the first responders were killed in a terror attack at a Minnesota mall.
The president was set to address supporters in Cedar Rapids, Iowa, just outside of Minneapolis.
Instead, the rally was rescheduled for Saturday, but was later reschedulhed and reschedulled again.
The event was to have been held at the Sioux Falls Convention Center.
But, the venue changed to the Veterans Memorial Auditorium.
“The Iowa state police and the city of Sioux Falls were notified of the canceled event,” a statement from the Sioux City, Iowa Police Department read.
“Due to a very serious threat to the safety of all participants and our community, we have canceled the event at the Convention Center.”
The rally was scheduled for Friday night, but the event was reschedule by the state police to Saturday morning, the statement continued.
The Iowa Republican Party, in a statement, said that the decision was made to cancel the event in the event of a serious threat.
“While we do not have the exact exact details of the threat, it is clear that this is a significant threat,” the statement read.
Trump has faced backlash for his controversial comments about law enforcement officers and the military.
He told supporters at a campaign rally in South Carolina earlier this month that the military and police are too powerful and that they shouldn’t be allowed to do their jobs.
He has also said that police officers should be killed and that police should be shot.
