In the midterm elections this fall, Republican candidate Matt Rosendale hopes to unseat incumbent Democrat Sen. Jon Tester — whom the president’s son, Donald Trump Jr., on Thursday afternoon called “Two-Faced Tester” before introducing his father to an exuberant crowd at the Four Seasons Arena in Great Falls, Montana.

“A vote for Jon Tester is a vote for Chuck Schumer, Nancy Pelosi, and the new leader of the Democrat party, Maxine Waters,” President Donald Trump then told the assembled crowd.

He called Matt Rosendale a “real Montana fighter.”

Trump held nothing back. He called out Tester for his abysmal voting record, ticking off several issues on which Tester voted against the president’s agenda. These included the repeal of the Obamacare individual mandate, the availability of late-term abortion, the travel ban, Justice Neil Gorsuch’s appointment to the Supreme Court, sanctuary-city policies, and a change in the tax code that eliminated the estate tax for many family farms.

The president also reiterated his support for U.S. Immigration and Customs Enforcement officials.

“They protect us, and we protect them,” he said of ICE.

He praised the courage of law enforcement officials and others who had to apprehend Therese Patricia Okoumou, the woman who climbed the base of the Statue of Liberty in New York City on July 4, and called her a “clown.”

Okoumou, an immigrant from the Democratic Republic of the Congo, put many officers and others in danger and spoiled the holiday for visitors to one of our country’s most cherished landmarks.

The president jokingly said he would have taken a different approach than the brave officers who got her down. He said he would’ve gotten a net — and waited it out.

Trump then shifted to the topic of his Supreme Court nominee. He told the crowd to be sure to tune in on Monday at 9 p.m., adding, “I think you’ll be extremely happy with the selection.”

Doubling down on his goal of ginning up support for Rosendale, the president explained another reason the senator currently holding the seat is unsuitable. Trump called Rear Adm. Dr. Ronny Jackson a friend and said he felt “guilty” about having asked him to serve as secretary of the Department of Veterans Affairs.

Jon Tester, Trump noted, had leveled “vicious” accusations at Jackson, clearly referring to Tester’s April comments that Jackson handed out prescriptions “like candy.” Facing a huge backlash, Jackson ultimately withdrew from the process.

Crowd chants of “lock her up” followed quickly on the heels of Trump’s comment that “Crooked Hillary” received “special treatment under the Justice Department.”

Trump then moved to a number of international issues, saying he planned to make it clear that certain NATO members must “start paying the bills.” He compared the United States’ paying 4 percent of GDP to Germany’s 1 percent, saying, “They kill us on trade,” and said America’s continued adherence to such arrangements renders us “schmucks that are paying for the whole thing.”

He also mentioned he would be meeting with President Vladimir Putin soon and that getting along with China and Russia is “a good thing.”

Trump acknowledged that some of his past rhetoric concerning North Korea could be cast fairly as “tough.” But he decried much of the media’s depiction of his successful negotiating strategy as “too nice.”

He also added a zinger about paying $0 for concessions from North Korea, comparing it to former President Barack Obama’s payment of $1.8 billion in cash in the disastrous Iran deal.

He also intimated that Obama would have loved to have met with North Korean leaders, but they would not see him. “Obama was very close to going to war,” Trump said.

During his speech, the president repeatedly called out the “crooked press,” pointing at cameras and media assembled in the back of the arena. He said most were “so dishonest” and “bad people” and referred to them as the “fake news media.” He did make a few exceptions: “Some of the finest people I know are journalists,” he said, though he added that 75 percent are “downright dishonest.”

Trump championed legal immigration on a merit system, noting that businesses are coming back to the U.S., wages are going up, and that we “need people.”

He warned that voting for Democrats is akin to voting for the notorious MS-13 gang to “run wild.” He also said Democrats “want anarchy,” adding, “They don’t know who they’re playing with, folks.”

Trump also took a moment to castigate Rep. Maxine Waters (D-Calif.) — who recently urged her followers to harass members of the Trump administration if they see them in public. He called her a “low-IQ individual,” estimating her IQ to fall in the “low 60s.”

One of the points that generated the most enthusiasm from the receptive audience centered on Sen. Elizabeth Warren (D-Mass.).

Trump joked that if he were debating “Pocahontas” — presumably in a debate during the 2020 presidential campaign season — he would challenge her to take a DNA test. To sweeten the deal, he kidded about giving a million dollars to her favorite charity if the DNA test revealed her heritage to be Native American.

He joked with the audience about not telling anyone his “secret plan” to resolve the matter of the senator’s ethnic heritage once and for all.

Ultimately, the crowd chanted, “Build the wall,” after Trump told the audience his promised wall along the U.S.-Mexico border is currently under construction in some areas. He intimated, though, that progress could come to a halt should Democrats such as Rosendale’s opponent, Jon Tester, keep their seats in Congress.

Trump touted recent success on the employment front, including 3.4 million new jobs, rising wages, and record low unemployment claims among African-Americans, Hispanics, and women. And he mentioned that the country’s economic policy could be summed up in three words: “Jobs, jobs, jobs.”
