“We have a problem and it needs to be dealt with. The ideal scenario is that families be kept together and returned expeditiously back to their country of origin,” he said on CBS's "Face the Nation."

"We sympathize with people that are coming here," he added. "America is the most generous country in the world and ideally you wouldn't put people through additional trauma once they came into the United States."

When asked about Trump’s tweet, Rubio said he would be open to changing it.

“But the better law to change is to secure our border and to send a clear message that you cannot continue to enter the United States illegally,” he added.

“It is actually inhumane not to secure our border because we are sending out a message that is encouraging people to come here. We have to understand a lot of these people that are crossing children are being trafficked here," he said. "They are being brought here by criminal groups that help guide them and often take advantage of them and brutalize them on the path towards the United States and the ability to cross that border is a magnet that is drawing this behavior.”
