WASHINGTON (AP) — President Donald Trump says the idea of putting solar panels on the wall he wants to build along the Mexico border sprang from his imagination. Actually, an AP Fact Check finds that others proposed it, back when he was criticizing solar power as too expensive.

In his Iowa speech Wednesday night, Trump also claimed beneficial effects to the economy from actions he has not yet taken.

And he declared that the "time has come" for a welfare moratorium for immigrants that has been in place for two decades.
