President Trump was in his element Wednesday night at a rally in Duluth, Minn., where supporters cheered him on as he blasted illegal immigration, praised his relationship with North Korean leader Kim Jong Un, promoted his new "Space Force" and mocked protesters.

In the roughly one-hour rally, the president jumped from topic to topic, as he often does, lightly touching on his decision earlier in the day to temporarily end family separation at the border. Mr. Trump said the U.S. will still be "tough" at the border, despite that policy change by executive order, a policy change Mr. Trump had said only days ago couldn't be done by executive order.

Mr. Trump also reiterated his claim that he will halt foreign aid to countries from which people immigrate illegally.

"They're not sending their finest," Mr. Trump said. "We're sending them the hell back. That's what we're doing."

In his wide-ranging speech, the president also blasted one protester for having long hair, saying he couldn't tell if the person was a man or a woman. He mocked another protester saying, "Goodbye, darling, goodbye, darling," and telling the individual to go home to "mommy."

The energetic crowd loved Mr. Trump's monologue.

"By the way, is there anything more fun than a Trump rally?" the president said at one point.

The president did not mention the GOP primary for governor, as some thought he might. He did praise GOP congressional hopeful Pete Stauber, running in Minnesota's 8th Congressional District.

Trump holding roundtable ahead of rally

Mr. Trump, as he often does before campaign-style events, decided to hold a roundtable discussion. On Wednesday, that discussion is about protecting American workers, although the White House didn't offer many details. Tariffs are almost certainly to be high-up in that discussion.

But in that meeting, the president focused some on immigration, saying Minnesota has certainly faced its own immigration problems. The president stressed the need for strong borders, and stopping people from coming into the country.

Power outages reported where people wait for Trump

According to local media in Duluth, where the president is headed for his rally tonight, much of downtown Duluth is without power -- including where people are waiting for Trump, without air conditioning.

Rally speech likely to cover a lot more than candidates

As with most Trump rallies, the president's remarks about candidates are all-but-certain to turn into something else.

Lately, he has been particularly vocal about immigration and the report released by the Justice Department's inspector general on Hillary Clinton email investigation. The president's rally comes after he has been expected to sign an executive order to keep families together at the border, after days of negative press coverage.

Mr. Trump often uses his rallies to bash Democrats, talk up the need to elect more Republicans in November, blast illegal immigration, tear into special counsel Robert Mueller's Russia investigation, and tout his tax overhaul.

A look at GOP Gov. Tim Pawlenty's critical comments of Trump

The rally in Duluth is supposed to be for for Pete Stauber, a Republican congressional candidate running in the traditionally Democratic 8th District. Home of the state's famed Iron Range, Minnesota is important ground for Trump as a place where his new tariffs on foreign steel could play especially well. The GOP primary is set for Aug. 14.

But Mr. Trump hasn't held back on his opinions of GOP incumbents he dislikes. The night before a primary for Republican Rep. Mark Sanford of North Carolina, the president blasted Sanford on Twitter and urged people to vote for his primary opponent. Sanford lost. On Capitol Hill Tuesday night, Mr. Trump again mocked Sanford in a meeting with House Republicans, reportedly calling him "nasty."Few Republicans have criticized Trump more strongly than Pawlenty, who is seeking his old job once more.

In 2016, Pawlenty said Mr. Trump was "unsound, uninformed, unhinged and unfit to be president of the United States" in the days after a recording of the presidential candidate making vulgar comments about women surfaced. After launching his campaign in April, Pawlenty said he still voted for Mr. Trump in 2016 and supports the president's policies.

Jeff Johnson, the state GOP's endorsed candidate for governor, has been stronger in his support of the president. He and his allies have portrayed himself as more in tune with the party's base and say Pawlenty -- who holds a huge fundraising advantage -- should be disqualified for his criticism of Trump.

Republican political operative Gregg Peppin said it's another chance for Mr. Trump to aid an underdog candidate who has been a loyal supporter.

"I think it's a pretty cut-and-dried case in this instance," said Peppin, who worked for another GOP candidate for governor who has since quit the race. "It presents the president with an excellent opportunity to test his theory. Whether he'll do that, remains to be seen."
