Sanders says defeating presumptive Republican nominee Donald Trump is his first priority.
Clinton last week clinched the nomination and won President Barack Obama's endorsement.
The last primary is on Tuesday in the District of Columbia.
Sanders tells NBC's Meet the Press that he wants to make sure Clinton commits to his priorities such as a minimum wage increase and climate change reform.
