In addition to contributing to CBO's analysis in one of CBO's divisions, interns participate in an educational program that includes briefings on the work that we do and the way we do it. CBO's interns also attend seminars, including the Congressional Summer Intern Lecture Series, which has featured former Speaker of the House Nancy Pelosi, former Secretary of State Colin Powell, Supreme Court Justice Ruth Bader Ginsburg, and journalist Cokie Roberts.
