Speaking to small business owners on Tuesday, Trump signaled he was not open to a half-measure that protects families without delivering to Trump the rest of his immigration wish list.
Migrant children are not permitted to be incarcerated with their parents, and are kept in separate facilities maintained by the Department of Health and Human Services.
Trump, who has made a tough stance on immigration a centerpiece of his presidency, has steadfastly defended his administration's actions. "Get it done, always keeping in mind that we must have strong border security".
"Democrats are the problem", he wrote.
As images of youngsters in cages and an audiotape of wailing children affected by Trump's "zero-tolerance" policy filled worldwide media, the overwhelming majority of Republicans in competitive districts in November's elections issued statements and took to social media to try to tell voters that they did not condone removing children from their parents.
Later, he declared during remarks at a hotel that he had no choice but to remove children from their parents at the border.
It was then announced that there will be an increase in criminal prosecutions of parents entering the United States illegally and their children would be placed in protective custody.
"They forget that we have constituents at home".
Donahue also urged lawmakers to act on the separation of families as well as "permanent protection for Dreamers, and permanent relief for long-term beneficiaries of the Temporary Protected Status (TPS) program".
He berated Democrats, calling them "the problem".

China spells out tariffs it plans on U.S. goods

He cited immigration for causing political instability in Germany and said that crime in Germany was "way up". But Trump reiterated the accusation on Tuesday. The Hill's Alexander Bolton observed: "Schumer said [Democrats] want to keep the focus on Trump".
At the same time, the President appeared to suggest the practice could act as a deterrent for future migrants considering entering the United States with their children.
There have been protests outside many detention centres and even after a growing national outrage, the USA president is unapologetic and has declared that the country will not be a "migrant camp". "We can not and will not encourage people to bring children by giving them blanket immunity from our laws", he said. "Otherwise it's never going to stop", he said.
He's argued that, "politically correct or not, we have a country that needs security, that needs safety". "Without a border, you don't have a country". "There is no other way to say it - this is not who we are, and it must end now", said Chamber President Tom Donohue. "Maybe it's politically correct or maybe it's not. We might as well get it right or let's just keep going", Trump said, signaling he wants an all-or-nothing immigration bill.
"We can either release all illegal immigrant families and minors who show up at the border from Central America, or we can arrest the adults for the federal crime of illegal entry", he said.
The separations, which have been blasted by Democrats, some Republicans, medical professionals, rights activists and clergy, began after U.S. Attorney General Jeff Sessions announced a "zero tolerance" policy in April in which all those apprehended entering the United States illegally would be criminally charged.
In the seven-minute tape, children who were reportedly aged four to 10, could be heard crying out for the parents.
That left members grasping for a happy message of unity afterwards - especially since Trump has been known to change his mind and publicly attack congressional Republicans over legislation.
"We want to end the border crisis by finally giving us the legal authorities and the resources to detain and remove illegal immigrant families all together and bring them back to their country", he said.
