An example of when the power of veto was used?

Explanation:

in 1792, George Washington exercised the presidential veto power for the first time; he would use the veto only twice during his presidency, and was never overridden. ... Roosevelt vetoed the most bills of any president in history, with 635. (He was overridden only nine times.)
