The Trump campaign on Monday night went after Minneapolis and the Target Center arena over security costs, which campaign manager Brad Parscale Bradley (Brad) James ParscaleMORE called "an outrageous abuse of power by a liberal mayor trying to deny the rights of his own city’s residents just because he hates the President!" In a press release the campaign said Frey's administration requested $500,000 ahead of the president's scheduled appearance this Thursday.

Later Tuesday morning Trump tweeted, "Someone please tell the Radical Left Mayor of Minneapolis that he can’t price out Free Speech. Probably illegal!"

Frey responded, "Someone tell the President of the United States that he can afford to help pay for the extra time our officers will be putting in while he’s in town."

Parscale on Tuesday echoed Trump, saying, "This is what the left is doing in America. Removing your 1st amendment rights!"

The mayor of Minneapolis, Minnesota @Jacob_Frey, is a radical left-wing nutjob that is limiting free speech. We will seek all legal remedies to force the Mayor to allow our constitutional rights.

Numerous cities have reported failures by the Trump campaign to pay back costs incurred by local law enforcement services involved in protecting the president and rally attendees.

"When one considers how much money campaigns raise and spend, it does not seem unreasonable to expect some degree of reimbursement for such demands for service,” Richard Myers, executive director of the Major Cities Chiefs Association, said in a statement.
