"Criminals, drug dealers and rapists" are all words Donald Trump has used in the past to describe undocumented immigrants living in the US.

As the Trump administration faces mounting troubles back in Washington, the president chose to deliver a presidential pitch to his supporters in Ohio on Tuesday night (25 July).

He told a large crowd that he "can be more presidential than any other president, with the exception of the late, great Abraham Lincoln".

At his sixth campaign-style rally since becoming president, Trump once again railed against immigrants at a rally, adopting nationalistic, anti-immigrant rhetoric reminiscent of his speeches on the campaign trail.

At a rally last year, Trump infamously referred to immigrants travelling across the US-Mexico border as "bad hombres".

"We're going to secure the border," he promised a large rally a month before the election. "We have some bad hombres here and we're going to get them out."

On Tuesday, he launched into another furious tirade against people who are living in the US illegally.

"One by one, we are finding the illegal gang members, drug dealers, thieves, robbers, criminals, and killers. And we are sending them the hell back home where they came from," he told the crowd.

He promised that "these predators and criminal aliens preying on innocent young people" would not find a safe haven in the US.

The president described undocumented immigrants as "animals" who "slice and dice young girls with a knife" because they want them to "go through excruciating pain before they die."

"They don't want to use guns, because it's too fast and it's not painful enough," he added.

"These are the animals that we've been protecting for so long. Well, they're not being protected any longer, folks," he said to loud cheers.
