Trump 2020 campaign manager Brad Parscale said that the city was trying to charge $530,000 for security and other costs, and claimed that this was out of scale with what they charged previous campaigns for similar rallies.
Asked about the Trump campaign charge that the city is severely overestimating the cost of the event, citing a $20,000 estimate for an event President Barack Obama held in 2009, Frey told reporters on October 8 it was different then because Obama was coming "on behalf of the office as president of the United States, not as a campaign event".
"The arena in Minneapolis has been fully approved", Parscale said in the email. "He's kind of making the whole city look bad, like we're not a diverse community that's tolerant of ideas".
It was just a warmup to Trump's first campaign rally since being engulfed in the swirl of an impeachment investigation, an event expected to pack an extra punch.
The mayor's office did not immediately respond to a request for comment.
Frey said when Trump's rally was announced last month that Trump's "message of hatred" was unwelcome.
Wayzata, Minn., resident Sheri Auclair said she's attended Trump rallies before and plans to get her photo taken with the president at his rally Thursday.
Carnahan, however, says Trump has done a lot for Minnesotans and the country including "more than 6 million new jobs created, historic lows for unemployment, the largest tax reform in a generation, there have been a lot of positive things that America has seen". "We're going to be coming into the city here and letting [Trump] know we love him, and support him".

It's created logistical and cost concerns for Minneapolis officials, who are asking for help from state, local and federal law enforcement agencies and expecting hundreds of thousands of dollars in extra costs for security. "We want families to come out here, we want everyone to come out here because this is about us", said Jaylani Hussein, executive director of the Minnesota chapter of the Council on American-Islamic Relations.
At a 2009 rally at the Target Center for then-President Barack Obama, security costs totaled around $20,000, according to a Pioneer Press report at the time. The letter said the Trump campaign "will aggressively pursue all remedies available to it in law or equity".
Frey added that he doesn't have time with a city of 430,000 people. "The quiet people who are more balanced in their opinions need to speak up".
Lt. Bob Kroll told "Fox & Friends" "It's disparate treatment" and added, "They have not charged almost that much for other events" held at the same location.
