"We've got to have a better tone going forward over the long haul for sure," Bush said. "You can't ask people to join your cause and then send a signal that you're really not wanted. It just doesn't work."
Bush emphasized that he believes it is important to secure the border and block illegal immigration. But he argued that allowing more young people to work legally in the country would boost economic growth.
"We need young aspirational people to come to our country so that we can grow over a sustained period of time at a high rate," Bush said.
Bush supports the Dream Act, which would give legal status to some young people brought to the country illegally.
