Which of these is a constitutional right to reject a decision or proposal made by a lawmaking body?

You make is sound like anyone has that power. You kinda have to be the president and when one does veto, they pay for it. Veto power can cripple any president.

It is actually a Latin word meaning: I forbid it.

America was a really great place until they elected a con man.

Gee I dunno do we have the right to “Veto” anything anymore?
