Harvard University is eliminating tuition fees for students from families with incomes of $200,000 or less, attempting to broaden access to the school at a time when elite universities are under attack from the White House and lawmakers.

The expansion of financial aid at Harvard, the oldest and richest US college, means the school will be free for families making $100,000 or less, with food and housing also covered. Students that meet the $200,000 threshold won’t pay tuition, according to a statement Monday.
