Thousands of people braved the heat Saturday and made their way to Veterans Memorial Coliseum to attend the campaign rally for presidential candidate Donald Trump.

The presumptive Republican nominee took the stage at about 4:20 p.m. Saturday with immediate promises of solving our country's problems.

"We're going to be very, very smart. We're going to be tough. We're going to be very vigilant, and we're going to solve our problems," he said.

Trump first addressed the Orlando massacre. "What happened was an assault on our country; it was an assault on the gay community," he said. He also said the mass shooting was not about guns; it was about terrorism.

The hot topic issue of immigration came up next. "We want people to come into our country...legally, legally," Trump said.

Trump made an appeal to female voters, saying, "We want women for Trump!"

He promised to bring jobs back, cut taxes and repeal and replace the Affordable Care Act. He also pledged to knock out Common Core.

Trump wrapped up his speech with a promise to reform education, veterans' and health care. "We're going to make America greater than ever before," said Trump in closing, as he exited the stage a few minutes after 5 p.m.

Trump's appearance was preceded by a speech by former Arizona Governor Jan Brewer, who said Trump will "fight to bring back the economy, and will bring jobs back to America, and reduce taxes." She also said he will make America strong, and protect Second Amendment rights.

Brewer was greeted with cheers when she said, "Donald Trump will build the wall."

Sheriff Joe Arpaio spoke next at the rally, giving Trump a ringing endorsement.

"I'm gonna stick by the guy until the bitter, or sweet, end," said Arpaio. (Later, during his speech, Trump returned the praise, saying, "Sheriff Joe, what a great guy! I love you!")

Arizona State Treasurer Jeff DeWit also welcomed Trump, stating, "Mr. Trump is one of the smartest and quickest minds of our time."

This was Trump's fourth campaign rally in Arizona since launching his bid for the White House one year ago -- and his first Valley visit since locking up his party's nomination.

Earlier in the day, people waited outside, some of them for several hours. One woman claimed she got in line at 5 am.

A crowd of protesters also gathered outside the Coliseum, but the demonstrations were mostly peaceful. Inside, one man had to be escorted from the premises due to his T-shirt slogan, which read "[expletive] Islam."
