A Texas man who brands himself 'the undeportable one' has changed his surname to Trump after the move was approved by a judge.

Heavily tattooed Ernesto Baeza Acosta filed a petition to change his name to Ernesto Trump, and called on the President to invite him to the White House.

The 34-year-old wrote on his petition: 'I want to use my new name because it is more suitable for professional purposes.'

Trump, who was born in Houston, said his parents entered the US from Mexico illegally 40 years ago.

He said his mother is upset about his name change as she is not a supporter of the President, The Smoking Gun reports.

Although he is a fan of the 45th President, he admitted he did not vote because he was not registered.

In a YouTube video, posted under the name Big Ern, he showed copies of his legal documents and said: 'Those are my legal documents, that's my real name.

'You can call me the undeportable one, you can call me the President's son or you can call me Ernesto Trump.'

Addressing the President directly, he said: 'Dad if you see this video I don't want no money with you I want to spend some father-son time with you. Maybe we could eat a hot dog, drink a pint of beer or go to the movies.

'Maybe I could go to see my step brothers and sister and step mom and eat dinner at the White House.'

And he told viewers: 'If you can tag the president, tell him his son, Ernesto Trump, wants some father-son time with him.'
