The rally, Mr. Trumpâs first since the end of April, served as a venting session for a pent-up president who has stewed and brooded from inside the gilded cage of the White House over attacks from investigators, Democrats and the news media, his interview schedule drastically pared down and his aides imploring him to stay off Twitter.
Style-heavy and substance-light, the speech went over an hour: an epic version of the fact-challenged, meandering and, even for his detractors, mesmerizing speeches he gave during his upstart presidential campaign.
Mr. Trump gave few details about his plan for the solar panels, beyond that it creates âenergy and pays for itself,â or about his coming proposal to greatly curtail welfare for new immigrants â including how it would differ from existing laws that do just that. He called it a âtotal rewrite of our immigration system into a merit-based system,â words consistent with the public tone he has struck on immigration restrictions.
The president, whose approval rating is mired below 40 percent, told the crowd of roughly 6,000 people at the U.S. Cellular Center that he was thrilled to be out of the âWashington swamp.â
He barely reacted to whistle-blowing protesters who interrupted him within the first five minutes of the speech, when he was honoring Representative Steve Scalise, the Republican House whip, who was shot during a baseball practice last week and now faces a long rehabilitation. âNever fails,â Mr. Trump said as the protesters were led out.
Free from his handlers for roughly 70 minutes, Mr. Trump described his administration as he wished it to be: one in which he had made historic governing accomplishments and been stymied solely by the âresistance.â
âI think health care is going to happen, and infrastructure is going to happen, and I look forward to being able to produce it,â he said.
He derided trade deals despite an Iowa economy that relies in part on exports. He denounced the $6 trillion spent and the lives lost in the Middle East over the last 15 years, despite his administrationâs decision to reauthorize troops in Afghanistan.
He toggled back and forth between telling farm-rich Iowa that he had fought for forgotten voters and lauding the wealth of Gary D. Cohn, his top economic adviser and a former executive at Goldman Sachs, the Wall Street giant that Mr. Trump derided in commercials in 2016.
âIn those particular positions, I just donât want a poor person â does that make sense?â he said of Mr. Cohnâs job and that of Commerce Secretary Wilbur Ross, another immensely wealthy man whom Mr. Trump lauded as a âlegendary Wall Street genius.â
âBrilliant business mindsâ are what the economy needs, he said.
And the president frequently embellished details during his speech, or told outright falsehoods. He tried to catch himself at one point, saying, âI have to be a little careful, because theyâll say, âHe lied!ââ
But he nonetheless plowed ahead, including misstating whether the Paris climate agreement, from which he plans to withdraw the United States, is binding. While doing so, he also prompted the audience to name the agreement themselves. âPâ¦ pâ¦ p,â he said.
âLike hell itâs nonbinding!â thundered Mr. Trump, who in fact called the accord nonbinding in his Rose Garden speech announcing the withdrawal this month.
âWeâre not even campaigning, and look at this crowd!â he said at another point. The rally was advertised, sponsored and organized by his campaign committee.
He also repeated his frequent, untrue campaign refrain that the United States is one of the worldâs highest-taxed nations.
The president dismissed the potency of wind-harnessed energy in a state filled with thousands of turbines. âI donât want to just hope the wind blows to light up your house and your factory,â he said, âas the birds fall to the ground.â
And he vented throughout against the news media: âthe fake news,â he said, one of his favorite and most therapeutic invocations.
Mr. Trump also condemned Democrats as âobstructionistsâ â but then added that he wanted to work with them and might be damaging those prospects. âBut who cares,â he concluded. He ignored the fact that Republicans hold majorities in Congress.
When he mentioned Hillary Clinton, the crowd lustily chanted, âLock her up,â as if the election had not taken place.
It was the first trip Mr. Trump had taken west of the Mississippi River since he became president. His opening acts included his pregnant daughter-in-law, Lara, who is married to his son Eric. She suggested that complaints against the president were generated by people who âare very scared of what heâs going to do.â
Jeff Kaufmann, the chairman of the Republican Party of Iowa, took an unusual shot at Senator Ben Sasse, Republican of Nebraska, a frequent Trump critic who has himself been perceived as a potential presidential candidate.
Throughout the arena, Mr. Trumpâs fans were adamant about whom they blamed for his troubles.
âWhat Iâm frustrated about, and I hear this, that people are saying heâs not doing anything â how can you do something if people are resisting?â said Wendy Lemke, 65, of Cedar Falls.
After Mr. Trump had talked for over 60 minutes, diverting from his teleprompter repeatedly, he decided to wrap it up. Someone in the crowd yelled that they did not want him to go.
âI donât want to leave, either!â Mr. Trump called back.
