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.

The response so far from financial markets has been skeptical as Trump seems unable to trim deficits as promised.

“All of this rhetoric about cutting trillions of dollars of spending has come to nothing — and the tax bill codifies that,” said Michael Strain, director of economic policy studies at the American Enterprise Institute, a right-leaning think tank. “There is a level of concern about the competence of Congress and this administration and that makes adding a whole bunch of money to the deficit riskier.”
