Jennifer Lopez has made an impassioned plea urging her fans to fight against the United States’ policy of separating immigrant children from parents being detained for illegally entering the country.

President Donald Trump agreed to stop the controversial practice in the face of mounting international criticism and now politicians are set to vote on new measures aimed at halting the separations.

Many celebrities joined the chorus of voices criticising the policy and now Lopez has described the issue as “about basic human rights and decency”.

In a lengthy Instagram post and alongside an image of a crying two-year-old girl being removed from her parents, the 48-year-old mother of two said: “Reading the news about the separation of children from their families, I can’t help but think about my own children. I cannot fathom a world where they would be ripped from my arms, taken to a place no better than a prison far from home.

“I feel we will never forget this moment in time. Bearing witness to these atrocities and that’s what they are, I can say for sure, remaining silent is not an option.”

She added: “As a Latino, and as you know very well, a proud Bronx born Puerto Rican American, we and the people of all different races, roots, and culture have enriched this country. But the recent rhetoric and constant dismissal of what we bring to the table has to stop. This is about basic human rights and decency.”

The singer and actress urged her followers to contact their congressman before adding: “I also want you to remain hopeful—hold fast to hope, faith and Love. ITS ALL IN OUR HANDS.”

âI REALLY DONâT CARE, DO U?â written on the back of Melaniaâs jacket, refers to the Fake News Media. Melania has learned how dishonest they are, and she truly no longer cares! — Donald J. Trump (@realDonaldTrump) June 21, 2018

On Thursday, Mr Trump’s wife, Melania, was criticised for wearing a jacket that read “I really don’t care, do u?” on her way to visit a facility housing migrant children separated from their parents.

Mr Trump said his wife was attacking the news media with the garment.
