Passions have been running high in recent days, with Republican and Democratic lawmakers, faith leaders, former first ladies and others up in arms over the family separations at the US-Mexico border.
For days, Trump and his top administration officials were unwilling to unilaterally reverse the separation policy, insisting that congressional action was required. Trump officials could not say how many of those children have been reunited with their mothers and fathers.
Carey spoke to CBS News about how the Trump administration's "zero tolerance" policy will affect America's reputation.
But Senate Democratic leader Chuck Schumer of NY signalled that no such support would be coming, saying it's already in Trump's power to keep the families together. Claire McCaskill, picked up on Trump's talking point and blamed Democrats - without addressing the reality that the family separations are the result of a Trump administration policy and without taking a position on the policy.
"We want security for our country", the president said Wednesday.
Republicans were scrambling to update their approach ahead of a visit from Trump, who called earlier in the day for Congress to approve what he called a third option to address the family separations.
The order says the Department of Homeland Security - and not the Justice and Health and Human Services Departments, as under previous policy - would have continuing responsibility for the families.More news: House rejects hard-right immigration bill, baring GOP divide
The ACLU are leading the opposition to the separation of families at the United States border, with a petition to the Secretary of Homeland Security that reads: "Stop separating children from their parents in immigration detention. I didn't like the sight or the feeling of families being separated".
President Donald Trump indicated he would take action shortly to both improve security on the border and help keep families together, speaking briefly with reporters Wednesday.
It's unclear what will happen to the families that have already been separated.
Republican Rep. Brian Fitzpatrick, who represents the suburbs north of Philadelphia, issued a strongly worded statement on Monday but did not mention Trump, instead calling on Congress to act to stop the separation of families.
"So what I'm asking Congress to do is to give us a third option, which we have been requesting since past year, the legal authority to detain and promptly remove families together as a unit", Trump said Tuesday.
The last-minute decision came at almost the same moment the House killed another more conservative immigration bill - also supported by Trump and GOP leaders - by a vote of 193-to-231.

Trump's said the order does not alter the "zero tolerance" policy itself that the administration put in place in April.
"We do not want children taken away from their parents", Ryan, R-Wis., said. Blame is also placed on the parents for putting their children in this position by illegally crossing borders with them.
Wednesday's order included the caveat that immigration authorities will not detain families together if "there is a concern that detention of an alien child with the child's alien parent would pose a risk to the child's welfare".
ICE operates two large family detention centers in Texas and a smaller facility in Pennsylvania, with a combined capacity for about 3,000 beds.
Republican leaders temporarily yanked a Trump-backed immigration bill from the House floor just hours before lawmakers were supposed to vote on it, a surprise move that seemed unlikely to improve its prospects for passage.
Representative Kristi Noem said Mr Trump told politicians he "would continue to support the legislation, and that people shouldn't be anxious that he would change his mind".
The measure would also offer protections to another vulnerable group - Deferred Action for Childhood Arrivals recipients - who are undocumented immigrants brought to the USA as children.More news: England World Cup game beats royal wedding in TV ratings
Cruz's bill would double the number of federal immigration judges, authorize new temporary shelters to house migrant families and limit the processing of asylum cases to no more than 14 days - a goal immigrant advocates say would be hard to meet.
