Donald Trump talks about the solar panel plan for the Mexican Wall
US President Donald Trump told supporters that his proposed wall on the Mexican border could hold solar panels.
At a rally in Iowa, he said the teams would provide cheap energy and help pay for controversial walls.
He suggested that the plan was his own and said: "Imagination is good, right? Okay? My thoughts."
However, solar panels have been included in the wall design submitted by the company.
During the campaign, Trump pledged to build a wall on the Mexican border to stop illegal immigration and drug trafficking.
He insisted that he would pay for Mexico, but President Enrique Peña Nieto had rejected the idea.
