Trump launched his Twitter war with Frey after the mayor sought a $530,000 deposit to defray expenses, mostly for security, ahead of Trump's Thursday rally at the Target Center in Minneapolis. The release said the Target Center passed those costs on to the Trump campaign at the threat of canceling the rally. "The cities dispatched police officers to secure Trump's events because they believe public safety required it - and the U.S. Secret Service asked for it".
At the eleventh hour, the boy Mayor of Minneapolis, Jacob Frey, has tried to block the rally by sending Target Center an absurd bill for "security".
Trump's campaign manager, Brad Parscale, accused Frey of "abusing his power".
"The lightweight mayor is hurting the great police and other wonderful supporters", Trump tweeted Tuesday morning.
Frey responded on Twitter: "Yawn. Welcome to Minneapolis where we pay our bills, we govern with integrity, and we love all of our neighbors", the mayor tweeted.
"The Campaign can not be in breach of an obligation it does not owe to AEG", the letter continues.
His campaign said the "bogus security charges" are an attempt to prevent Minneapolis residents from supporting Trump.
The City of El Paso confirmed to ABC News on Tuesday that the bill has still not been paid by the Trump campaign-and the city of Minneapolis has taken notice, even reaching out to the City of El Paso regarding the bill, according to El Paso Communications Director Laura Cruz-Acosta.
In the past, Frey has spoken out against the president, calling his actions "reprehensible" and saying that Trump's "message of hatred will never be welcome in Minneapolis", the Minneapolis Star-Tribune reported.
Trump's campaign has a reputation for not repaying cities for costs associated with his rallies.
