President Obama has called for comprehensive immigration reform in the United States.

The president said the country needs a system that upholds the law, while also upholding the nation's tradition as a land of immigrants.

He said border security and employment verification need to be addressed. And he said there should be a pathway to legal status for some of those in the country illegally, including young people who live here now, and who were brought to the U.S. by a parent or someone else.
