Mondale was the first vice president to have an office in the White House and established the concept of an "activist Vice President." He began the tradition of weekly lunches with the president, which continues to this day. More importantly, he expanded the vice president's role from figurehead to presidential advisor, full-time participant, and troubleshooter for the administration.
