The Question: Which President first included his Vice President in Cabinet meetings?
Warren G. Harding
The role of Vice President has had varying levels of importance over the years. In the early days of the nation, it was more decorative than functional — John Adams himself called it “the most insignificant office.” But in the 20th century, Presidents started to bring their VPs into critical meetings. Warren G. Harding, who served in office from 1921 to 1923, was the first to give his Vice President, Calvin Coolidge, a seat in the Cabinet.
The correct answer is Warren G. Harding.
