President Donald Trump marked the first 100 days of his second term in the White House on Tuesday with a rally, where he promoted his achievements, especially on immigration.
Mr Trump gave a speech at the event, held at community college to the north of Detroit, Michigan, a battleground state he flipped in last year's election and home to the US car industry.
Large signs on the walls read, “Buy American, hire American" and "The American dream is back".
The Republican, who took office on January 20, highlighted his hardline policies on immigration, his signature topic.
"Democrats have vowed mass invasion and mass migration. We are delivering mass deportation, and it's happening," Mr Trump told the cheering crowd before displaying a video showing handcuffed men being shoved by masked officials while apparently being deported.
At the White House this week dozens of signs dotted the well-tended lawn, with the mugshots and names of migrants accompanied by the crimes they allegedly committed, along with the word "arrested".
In a document titled Promises Made, Promises Kept, the White House said more than 150,000 migrants have been arrested so far and the number of illegal crossings along the US-Mexico border has plunged.
At least 139,000 migrants have been deported, while others have been sent to a prison in El Salvador or the US detention centre in Guantanamo Bay, Cuba.
"President Trump's central campaign promise was to secure the border and end this invasion in just under 100 days," press secretary Karoline Leavitt told reporters on Monday. "The President has overwhelmingly delivered on that promise."
Mr Trump, with the help of his billionaire adviser Elon Musk, has cut government spending and shut down several government agencies, sending shockwaves around Washington.
He said the move was necessary to root out corruption and unnecessary spending. He has also cut programmes aimed at promoting diversity, and gender and racial equality.
Mr Trump also imposed tariffs on trade partners and allies, upsetting the global economy. He has explained away the levies as measures aimed at ending economic imbalances and moves that would enrich the US.
During his campaign and after, he said "tariff" is the "most beautiful word in the dictionary". Economists have widely panned the tariffs policy as an inflationary risk that could result in delays getting goods on shelves.
On Tuesday, Mr Trump signed an executive order relaxing some of the levies on cars and vehicle parts.
The order gives "partial tariff rebates to any company that assembles its cars right here in the USA", Mr Trump said at the rally. "In other words, I'm giving them a little bit of a break, right? They took in parts from all over the world. I don't want that. I want them to make their parts here, but gave them a little bit of time."
Treasury Secretary Scott Bessent said the goal remained for car makers to "bring back" production to the US.
"President Trump has had meetings with both domestic and foreign auto producers, and he's committed to bringing back auto production to the US," Mr Bessent said. "President Trump is interested in the jobs of the future, not the jobs of the past."
