After a fair amount of haggling, Sioux City officials were able to get the people planning a rally featuring former President Donald Trump to pay a $5,000 bill the day before last month’s event, but the city is still waiting on the U.S. Secret Service and event planners to reimburse more than $11,000 in other rally costs.

Two top Iowa Republicans who were both up for re-election, Gov. Kim Reynolds and U.S. Sen. Chuck Grassley, both appeared at the event.

The Sioux City Journal reports that 136 pages of emails it obtained from the city show that officials went back and forth with representatives of Event Strategies Inc. for days before that company paid the $5,000 rental fee it agreed to for the use of several city parking lots for the Nov. 3 airport rally.

The biggest outstanding bill related to the rally is the $10,002.38 charge for police officers to staff the event that the Secret Service agreed to pay. City Finance Director Teresa Fitch said the city hadn’t been reimbursed for that as of Tuesday.

The other lingering bill is a $1,425 charge that Event Strategies is supposed to pay for having emergency medical services on standby at the rally.
