However, during a rendition of "God Bless the USA," some attendees began to sing along and raise their hands in an almost religious way.
"People were being ushered into a deeply religious experience," Tooley wrote, "and it made me completely uncomfortable.
"I love my country; I honour those who sacrificed their lives for our freedom and I respect our history and what we stand for, but what I experienced in that moment sent shivers down my spine. I felt like people were here to worship an ideology along with the man who was leading it. Don't get me wrong, it wasn't the song per se - it was this inexplicable movement that was happening in the room. It was a religious zeal."
Tooley could not immediately be reached, and the White House did not immediately respond to a request for a comment.
On Saturday, Tooley said, he talked his daughter into going with him to the rally in Melbourne, near Orlando.
"After all, how many times do you get to see the President of the United States in person - let alone in your hometown?" Tooley wrote. "I was eager for her to have this experience. It has to be a pretty cool thing, as a kid to see Air Force One, the President and the First Lady."
Once the duo made it through the lengthy line, he said, they were handed pom-poms and signs reading, "Make America Great Again!"
They were then ushered into a massive crowd at Orlando Melbourne International Airport.
The music, he said, moved from patriotic to pep rally - "more Star Wars themed." Then Air Force One rolled up to the airplane hangar.
"As they entered the venue and walked to the platform, there was terrific celebration," Tooley wrote. "I have been in the room when other Presidents were in a similar mode - it is always such a meaningful experience to be that close to them, regardless of whether or not you view them with adoration. Theeeee President of the USA!"
"The First Lady approached the platform and in her rich accent, began to recite the Lord's prayer," he added. "I can't explain it, but I felt sick. This wasn't a prayer beseeching the presence of Almighty God, it felt theatrical and manipulative. People across the room were reciting it as if it were a pep squad cheer. At the close of the prayer, the room erupted in cheering. It was so uncomfortable. I observed that Mr Trump did not recite the prayer until the very last line, 'be the glory forever and ever, amen!' As he raised his hands in the air, evoking a cheer from the crowd, "USA! USA! USA!"
Trump told the crowd he wanted to speak of "our incredible progress in making America great again" - but "without the filter of the 'fake news.'"
Although the past several presidents have waited more than two years each before jumping back onto the campaign trail, Trump's first four weeks in office have shown that he just can't stand too much time in Washington, as the Washington Post's Jenna Johnson reported.
One adviser calls political rallies the president's "oxygen" - and Trump seemed to direly need a deep inhalation following a week that included his national security adviser resigning and his top replacement pick turning him down, his nominee for labour secretary withdrawing from consideration and accusations involving his campaign and Russia.
"Life is a campaign," the president told reporters aboard Air Force One. "Making our country great again is a campaign. For me, it's a campaign."
During the presidential rally, Tooley, the pastor from Florida, said that Trump's speech evoked an "angry response from the crowd" toward others.
He wrote:
I heard two ladies off to my left chanting, not yelling or screaming but chanting, "T-R ...U-M-P; that's how you spell - bigotry!" They repeated the rhyme over and over.
"I'm trying to separate how I actually feel about this man and his campaignisms," Tooley wrote. "I know why people voted for him; I know why people voted against his opponent. But, at the end of the day, what I felt from his leadership in this experience was actually horrifying. There was palpable fear in the room. There was thick anger and vengeance. He was counting on it. I don't think I'm exaggerating when I say that it would not have taken very much for him to have called this group of people into some kind of riotous reaction."
