Comedian George Lopez has declared all of Donald Trump's children as fair game - including 13-year-old Barron - after he labeled the minor an 'anchor baby' born to an immigrant mom.

The 58-year-old posted an image to Instagram showing the teen son of the president alongside First Lady Melania Trump with sombrero hats superimposed on.

Above them he pasted a picture of three of Trump's older children - Ivanka, Eric and Don Jr - with their mother Ivana.

Both Ivana and Melania have 'immigrant' written below their image while the children are labeled as 'anchor babies'.

That term is said to refer to a child being born to a non US citizen mother where birthright citizenship is offered.

Lopez captioned the picture: 'Uh , @icegov “ if your listening “ you can find these immigrants at 1600 Pennsylvania Ave - Signed Enrique Enpanada the third #vivalaraza #45melapela.'

The image is accompanied with Mariachi music.

When questioned about the post by reporters in New York Lopez defended bringing Trump's children into the immigration debate.

Asked if it 'was fair' to put Barron in the post Lopez laughed and replied: 'Why? Is it fair to put kids in cages? They're kids.

'Let's go to ancestry.com and 23andMe. Everyone is swabbing the inside of their mouths to find out where they came from.

'And you know what we can all agree on? Is that nobody is from here. Immigration has always been a problem and it will continue to be a problem but only targeting Latinos is not good.'

When asked if Trump deserved some credit at his handling of the increasing tensions with Iran Lopez hit back: 'Almost bombing for shooting down a drone? I hope this airs before he ends the world.'

Trump's first wife Ivana became a US citizen in 1988 - after her children with the now president were born. For Melania it was 2006, the same year Barron was born, but it is not clear in what month.

The president has been criticized for separating immigrant children from their parents at the southern border.

U.S. immigration authorities had planned to launch a sweeping effort to deport recently arrived families who are in the United States illegally on Sunday.

But in a tweet on Saturday afternoon Trump said: 'At the request of Democrats, I have delayed the Illegal Immigration Removal Process (Deportation) for two weeks to see if the Democrats and Republicans can get together and work out a solution to the Asylum and Loophole problems at the Southern Border.

'If not, Deportations start!'

Trump has made illegal immigration a centerpiece of his administration and is likely to highlight it in his campaign for the 2020 election.
