Where did it come from?
In 1823, President James Monroe articulated a new foreign policy intended to oppose European colonialism and interference in the Western Hemisphere of the world and specifically the independent Americas. It demanded a commitment of non-interference from European powers and the U.S. made an equal promise to stay out of European affairs.
Where you may have seen it in history...
The Monroe Doctrine has been invoked sporadically over the nearly two decades since its establishment. In 1904, President Theodore Roosevelt expanded the policy with a more aggressive stance justifying United States intervention in the affairs of other countries in the Western Hemisphere. In 1962, President John F. Kennedy symbolically invoked the policy symbolically in the face of Russian aggression during the Cuban Missile Crisis.

In the wake of the United States' strike on Venezuela and detainment of the country's leader, the President cited the Monroe Doctrine as justification for the operation.
