YouTuber-turned-boxer Jake Paul was seen profusely sweating in an appearance with US President Donald Trump at a political rally.

Paul joined Trump on stage at Verst Logistics in Kentucky and was given the chance to address the crowd.

The 29-year-old went viral on social media, not for his comments about Trump and American manufacturing, but instead about his appearance.

Many pointed out vast sweat patches that were visible on Paul's beige suit as he spoke to the crowd.

The patches were particularly prominent under his armpits, which were exposed further when he raised his arms to the crowd.

Paul had previously spoken about how sweating had long been a major insecurity of his.

Paul made the revelation back in 2024 when he launched a deodorant brand W, which he and his brother Logan promoted before and after his bout with Mike Tyson.

'Sweating has been a longtime insecurity of mine,' Paul had said when launching the brand.

'If you know me, you know I'm a clean freak. I always want to smell fresh, but training in Puerto Rico's humid climate makes it a real challenge. 

'I needed a product that could keep up with my lifestyle — one that smells amazing but isn't full of junk ingredients, and honestly, one that wasn't from 2006. 

'That's why I started W… to create products for guys that will boost their confidence and smell amazing, but also don't cost $20 for a stick of deodorant.'

The W deodorants are claimed to offer 24 hours protection, with the brand website stating:  'With doubled scent load, increased hydration and more sweat-blocking power, our new deodorant and body wash are a monumental breakthrough for mankind (or at least for your morning)'.

During the event, Trump signalled that Paul's influence could eventually shift from the boxing ring to the halls of government in the coming years.

'I'm going to make a prediction that you will be, in the not too distant future, running for political office,' Trump told the fighter and the assembled supporters.

'And you have my complete and total endorsement.'

Paul had expressed his admiration for Trump credited him with teaching him the fundamental values of grit and resilience.

'We need more factories like this thriving all over the country,' Paul added. And I know [Trump's] going to be the one to bring that here to us.

'I know God is with us. I know he wants us on the right side of history, and everyone here has to do their part.

'And God's got us. Trump's got us. God bless.'

Trump returned the praise, telling the crowd: 'He's a great guy. He's a courageous guy and a talented guy. He's a hell of a fighter, too, by the way.' 

The endorsement of Paul's fighting spirit comes as the 29-year-old continues to dominate headlines following his endeavours in the boxing ring over recent years.
