Here are five highlights from Trump's campaign speech:

Ratcheting up criticism of North Korea's 'Little Rocket Man'

Trump continued to escalate his verbal battle with North Korean leader Kim Jong Un, modifying his nickname for Kim as "Little Rocket Man."

"This shouldn't be handled now. But I'm going to handle it because we have to handle it. Little Rocket Man. We're going to do it. Because we really have no choice choice. We really have no choice," Trump said.

The president also blasted past administrations' handling of North Korea.

"We can't have mad men out there shooting rockets all over the place," Trump said.

"He should have been handled a long time ago by Clinton. I won't mentioned the Republicans, by Obama," he continued, referring to past presidents Bill Clinton William (Bill) Jefferson ClintonBattle lines drawn on precedent in Supreme Court fight Sunday shows - Ruth Bader Ginsburg's death dominates Bill Clinton on GOP push to fill Ginsburg vacancy: Trump, McConnell 'first value is power' MORE and Barack Obama Barack Hussein ObamaDemocratic Senate campaign arm outraises GOP by M in August A federal court may have declared immigration arrests unconstitutional Blunt says vote on Trump court nominee different than 2016 because White House, Senate in 'political agreement' MORE.

The president's comments come after Kim issued a scathing statement in response to Trump's speech at the United Nations General Assembly this week, in which Trump referred to Kim as "Rocket Man." Kim later called the president a "mentally deranged dotard."

North Korea's foreign minister also threatened to test a hydrogen bomb in the Pacific Ocean as a response to Trump's U.N. address.

Swiping at John McCain for ‘terrible’ health-care decision

The president also took aim at Sen. John McCain (R-Ariz.) at the rally, just hours after the senator announced he would vote "no" on the latest Senate GOP effort to repeal and replace ObamaCare.

Trump called McCain's decision "totally unexpected" and "terrible."

"John McCain, if you look at his last campaign, it was all about repeal and replace, repeal and replace," Trump said. "So he decided to do something different, and that's fine."

“I cannot in good conscience vote for the Graham-Cassidy proposal. I believe we could do better working together, Republicans and Democrats, and have not yet really tried," McCain said in a statement.

Senate GOP leaders have to get 50 senators for Vice President Pence to cast a tie-breaking vote for the repeal bill before a Sept. 30 deadline expires to pass the measure with majority support.

Blasting NFL players who protest the national anthem

Trump's campaign rally Friday night covered issues beyond legislative and international affairs.

The president slammed NFL free agent Colin Kaepernick, saying NFL owners should fire players who kneel during the national anthem.

"Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, 'Get that son of a bitch off the field right now. He is fired,' " Trump said.

"Luther and I and everyone in this arena tonight are unified by the same great American values. We're proud of our country. We respect our flag."
