WASHINGTON (AP) — President Donald Trump faces the challenge of convincing Republican senators, global investors, voters and even Elon Musk that he won’t bury the federal government in debt with his multitrillion-dollar tax breaks package.

CEO Elon Musk swiped at the large Republican domestic policy bill making its way through Congress, in a notable break from President Donald Trump.

The president is touting his massive tax breaks bill to repair the U.S. debt, but some are expressing concerns if his legislation can actually trim the nation's deficit.
