Why is the U.S. separating migrant children from their families?

US Border Patrol agents speak to suspected immigrants near the US-Mexico border in McAllen Texas

Bush's op-ed comes on the heels of current first lady Melania Trump's spokeswoman weighing in on the issue on her behalf.

Former first lady Michelle Obama is adding her voice to the rising chorus of criticism of the Trump administration's policy of family separation at the border.

That's a rare move for Bush, who hasn't gotten involved in much political debate since her husband left office.

Another former first lady, Former Secretary of State Hillary Clinton, on Monday called the Trump administration's "zero tolerance" policy that has separated children from their parents at the southern usa border "a moral and humanitarian crisis".

Since the policy was enacted both Democrats and Republicans have spoken out against Trump and his administration. And it breaks my heart.

Attorney General Jeff Sessions recently directed border and immigration authorities to implement a zero-tolerance policy for prosecuting individuals who enter the US illegally.

On Tuesday, President Trump is set to meet with Congress to discuss immigration, with two bills that will be heard on the house floor this week.

The White House's hard-line posture comes as a growing number of Republicans are joining Democrats to urge the administration to change its policy on family separations.

Steve Bannon: "It's a crime to come across illegally, and children get separated".

Trump has said he wants the separations to end, but continues to blame opposition Democrats for the crisis, which critics say is one of his own making. A group of congressional lawmakers on Sunday visited a facility where families are being held at the border and were set to visit a longer-term shelter holding around 1,500 children - many of whom were separated from their parents.

Bush compared the Trump Administration's policy to the internment of the Japanese during World War II. "And it can be taken care of quickly, beautifully", he said.

The public outcry in the wake of images and stories of the children caught in the middle of the controversial immigration policy has sparked fierce debate. Pope Francis posted a tweet last week that some interpreted as referring to the new USA practice of placing migrant children in centers separate from their parents.

"I would cite you to the Apostle Paul and his clear and wise command in Romans 13, to obey the laws of the government because God has ordained the government for his purposes", he said. Trump falsely claimed that the separation of families was a result of a Democratic Party policy, and said it could only end when Democrats came to the table to negotiate broad immigration legislation that included funding for his border wall.

In the six weeks between April 19 and May 31, the Department of Homeland Security has sent almost 2,000 children to mass detention centers or foster care.

United States immigration law does not require families to be split up at the border. We need borders, we need security.

Dimmit County Sheriff Marion Boyd said most of the occupants were believed to lack legal permission to be in the US.
