On April 5, 1792, George Washington cast the first Presidential veto. From the article:

Presidential Vetoes
Article I, section 7 of the Constitution grants the President the authority to veto legislation passed by Congress. This authority is one of the most significant tools the President can employ to prevent the passage of legislation. Even the threat of a veto can bring about changes in the content of legislation long before the bill is ever presented to the President. The Constitution provides the President 10 days (excluding Sundays) to act on legislation or the legislation automatically becomes law. There are two types of vetoes: the “regular veto” and the “pocket veto.”
The regular veto is a qualified negative veto. The President returns the unsigned legislation to the originating house of Congress within a 10 day period usually with a memorandum of disapproval or a “veto message.” Congress can override the President’s decision if it musters the necessary two–thirds vote of each house. President George Washington issued the first regular veto on April 5, 1792. The first successful congressional override occurred on March 3, 1845, when Congress overrode President John Tyler’s veto of S. 66.
The pocket veto is an absolute veto that cannot be overridden. The veto becomes effective when the President fails to sign a bill after Congress has adjourned and is unable to override the veto. The authority of the pocket veto is derived from the Constitution’s Article I, section 7, “the Congress by their adjournment prevent its return, in which case, it shall not be law.” Over time, Congress and the President have clashed over the use of the pocket veto, debating the term “adjournment.” The President has attempted to use the pocket veto during intra- and inter- session adjournments and Congress has denied this use of the veto. The Legislative Branch, backed by modern court rulings, asserts that the Executive Branch may only pocket veto legislation when Congress has adjourned sine die from a session. President James Madison was the first President to use the pocket veto in 1812."
