This is the typical process with executive orders, as it requires a number of moving parts legally and the input of the Office of Legal Counsel.
"ICE is committed to connecting family members as quickly as possible after separation so that parents know the location of their children", the spokesperson added.
'Of the 12,000 children, 10,000 are being sent by their parents on a very risky trip, and only 2000 are with their parents, many of whom have tried to enter our Country illegally on numerous occasions.
The Texas Civil Rights Project works to document the separations in the hopes of helping them reunite with the children.

"So we're going to have strong, very strong borders, but we're going to keep the families together", Trump said Wednesday when signing the order.
President Trump also tweeted at 10:41 A.M. ET on Wednesday that the situation was "Democrats ['] fault", but that he was "working on something".

Prior to Trump's remarks, White House aides refused to comment on rumors of an executive order and Republicans on Capitol Hill seemingly had no knowledge of a coming executive action.

News reports in recent days in the USA have been filled with emotional images of young children at the border crying for their parents.
Trump continued blaming Democrats for the situation at the border.
