WASHINGTON — First lady Michelle Obama says a high school education is not enough in today's global economy.

Mrs. Obama tells a group of students that young people must go to college or get some type of professional training.

The first lady toured Howard University on Thursday with high school juniors and seniors from her hometown of Chicago. They visited a dorm, the grassy quadrangle area known as "The Yard," and the Punch Out cafeteria.

The visit is a part of Mrs. Obama's push to promote higher education, especially President Barack Obama's "North Star" goal for America, by 2020, to once again have the highest proportion of college graduates in the world.

After the campus tour, the first lady led a discussion moderated by rapper and TV host Bow Wow.
