Who vetoes bills?

What does this answer mean?

The President of the United States vetoes bills. To veto means to reject a bill that Congress has passed, so that it doesn't become law.

Under Article I, Section 7 of the Constitution, when the president vetoes a bill, it goes back to the part of Congress where it started, along with the president's objections. Congress can still make the bill a law by overriding the veto, but that takes a two-thirds vote in both the House and the Senate, which is hard to reach.

The veto is a clear example of checks and balances. Congress writes the laws, but the president can block them, and Congress can overcome the president's block only with broad support.

Vetoing bills is also one of the accepted answers to "Name one power of the president."

This is one of the 20 questions on the 65/20 list. At the interview, say "the President."
