President Donald Trump on Wednesday promised that every American adult would be given $5,000 from the federal government if his Republican Party succeeds in keeping control of Congress in midterm elections.

"So if the Republicans win, you win with us and you get $5,000. It will be called the Trump dividend," Trump told Republicans in Texas, as the party struggles in polls against the Democrats.

He did not say where the money would come from, citing only that "our country is making so much money."
