US President Donald Trump is musing about putting solar panels on his proposed wall on the Mexican border.
Trump suggested at a rally Wednesday night in Iowa that a solar wall would "create energy and pay for itself".
He then joked it would mean Mexico "will have to pay much less money" to build it.
Trump claimed as a candidate that Mexico would fully fund his impenetrable border wall - a plan Mexico rejected.
Trump also suggested the panels would make the wall "beautiful" and then praised himself by saying, "Pretty good imagination, right? It's my ideas."
The wall, which was a signature campaign promise, has not been at the centre of the White House's agenda and has been rejected thus far by Congress.
Trump on healthcare
Trump told supporters he urged Senate Republicans to add more money to their healthcare plan because he wants a plan with "heart".
"I've been talking about a plan with heart. I said, 'Add some money to it!'"
He also suggested he would be willing to change the bill Republicans were crafting if Democrats would come onboard.
He said "a few votes from the Democrats, it could be so easy" and "so beautiful".
Republicans have been working on a plan to repeal and replace former President Barack Obama's signature healthcare law.
Top Senate Republicans are expected to release the plan on Thursday.
