The president of the Minneapolis Federation of Police Officers denounced that Democratic Mayor Jacob Frey is discriminating against President Donald Trump, who plans to hold a rally in the city on Thursday, Oct. 10.

The president’s campaign manager said on Fox News that Frey is committing an “abuse of power” by trying to charge the president’s team more than half a million dollars in security for using the Target Center for the event.

“This is 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!” Brad Parscale wrote on Twitter.

Lt. Bob Kroll told “Fox & Friends” “It’s disparate treatment” and added, “They have not charged nearly that much for other events” held at the same location.

“The radical leftist mayor of Minneapolis, Jacob Frey, is abusing the power of his office and attempting to extort President Trump’s re-election campaign by conjuring a phony and outlandish bill for security in an effort to block a scheduled Keep America Great rally,” Trump’s campaign team explained in a statement.

In addition, the Democratic mayor made public, just 24 hours after the Trump rally was announced, the implementation of a new municipal law prohibiting off-duty police officers from attending the event, something that, according to Lieutenant Kroll, has never happened in other election campaigns.

The police assured “Fox & Friends” that, in rallies of Democratic presidents such as Barack Obama or Bill Clinton, not only were the police allowed to wear their uniforms, but “they were ordered to stand behind these presidents.”

However, the police union assured that this measure will not stop sympathizers of the Republican candidate inside the body from showing their support and told “Fox & Friends” that they have sent red T-shirts that read, ‘Cops for Trump’ that have already run out.

“So, we just thought you know what we’ll turn the place into a sea of red with the shirts we designed. And, they’re available and we can’t keep them on the shelves. They’ve been selling out as fast as they come in!” said Lt. Kroll.

Minneapolis Police Chief Medaria Arreondo denied in a press conference that the measure “is not showing favor or bias toward a particular political party or candidate,” adding, “I don’t want the Minneapolis Police Department to be politicized at all.”

President Donald Trump reacted to the controversy on Twitter by assuring that they want to limit freedom of speech.

“Somebody please tell the Radical Left Mayor of Minneapolis that he can’t price out free speech. Probably illegal! I stand strongly and proudly with the great Police Officers and Law Enforcement of Minneapolis and the Great State of Minnesota! See you Thursday night,” he wrote on Twitter.

Trump also thanked the police officers who defended their right to show their support for their president as security forces.

“Thank you to Lt. Bob Kroll of the great Minneapolis Police Department for your kind words on @foxandfriends. The Police are fighting the Radical Left Mayor, and his ridiculous Uniform Ban. Actually, I LOVE the Cops for Trump shirts. Want to bring some home. I am with you 100%!” the president said.

So far, and according to Trump himself, 72,000 people already have their ticket [which is free].

“The lightweight mayor is hurting the great police and other wonderful supporters. 72,000 ticket requests already. Dump Frey and Omar! Make America Great Again!” he tweeted, referring to Rep. Ilhan Omar (D-Minn.).

President Trump’s campaign team announced in a statement that they are considering suing the company that manages the Target Center.

“We are well aware of Mayor Frey’s vocal partisan opposition to President Trump and calls to disrupt the rally,” read a letter from Trump law firm Jones Day to the Target Center’s management firm.

“This last-minute squeeze seems to be nothing but a pretextual political effort with serious First Amendment ramifications,” the letter added.
