Sen. Marco Rubio delivered a short speech about education on Wednesday, discussing the need to modernize education for a new century and ensure that students receive the skills necessary to succeed in the changing job market.

Speaking at the U.S. Chamber of Commerce as part of a larger event on coordination between the business community and educational institutions, the likely 2016 presidential contender said that a “fundamental obstacle to economic progress is the skills gap that exists in our nation. The fact of the matter is that millions of our people do not have the skills that they need for the 21st century.”
