He cited cost estimates of $14-20 billion to build the 2000-mile long border wall.
Earlier this week, Cruz introduced legislation that would earmark assets seized from Guzman and any other Mexican drug lord convicted in the United States for the wall.
Guzman is currently in a New York City jail awaiting trial following his extradition in January to the United States.

In addition to drug trafficking, Mexican drug cartels have reportedly expanded into human trafficking and migrant smuggling on both sides of the US-Mexico border.
