President Donald Trump ripped Minneapolis Mayor Jacob Frey Tuesday after the “lightweight” Democrat lawmaker exorbitantly inflated the price of security for the president’s campaign rally.

Frey is “abusing the power of his office and attempting to extort” the Trump campaign by “conjuring a phony and outlandish bill for security in an effort to block a scheduled Keep America Great Rally,” the president’s campaign charged.

AEG, the company that manages the city’s Target Center arena, is charging the Trump campaign a whopping $530,000 for rally security. While Target has paid for naming rights of the arena, the Target Center is owned by the City of Minneapolis and Target has no role in its management.  

Target Center insists the campaign must pay the fee, but Trump campaign officials are pushing back and threatening to sue if the city does not honor the contract.

“The Trump campaign informed the Target Center that the U.S. Secret Service is solely responsible for coordinating security and that withholding the use of the arena would be viewed as a breach of contract and result in court action,” the Trump campaign said in a statement.

The campaign also noted a rally former President Barack Obama hosted at the Target Center in 2009 cost a mere $20,000.

The Trump law firm Jones Day issued a letter to AEG threatening legal action.

“We are well aware of Mayor Frey’s vocal partisan opposition to President Trump and calls to disrupt the rally,” the letter states. “This last-minute squeeze seems to be nothing but a pretextual political effort with serious First Amendment ramifications.”

The president blasted the Democrat mayor Tuesday morning, warning Frey is a “radical” and signaled he plans to show up to the rally despite the mayor’s ultimatum.

“Someone please tell the Radical Left Mayor of Minneapolis that he can’t price out Free Speech. Probably illegal!” Trump tweeted Tuesday morning. “I stand strongly & proudly with the great Police Officers and Law Enforcement of Minneapolis and the Great State of Minnesota! See you Thursday Night!”

Minneapolis voters should “dump” Frey and radical Minnesota Rep. Ilhan Omar and “Make America Great Again,” the president declared.

Frey is a regular critic of Trump and has previously called the president’s actions “reprehensible.” In September, Trump’s announcement of his plans to visit the city ignited outrage amongst leftists activists, the Minneapolis Star Tribune reported. Frey lamented he is unable to stop the president from visiting but assured, Trump’s “message of hatred will never be welcome in Minneapolis.”

Frey responded to Trump’s slights with sarcasm.

“Yawn,” Frey tweeted. “Welcome to Minneapolis where we pay our bills, we govern with integrity, and we love all of our neighbors.”

“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,” he shot back.
