Some commentators suggest that Trump is rushing the tax announcement to give his administration a shot in the arm before the symbolic marker of its 100th day. He may be able to achieve it, but only temporarily. Mnuchin said the administration's tax plan would focus on a middle-class tax cut, tax simplification, and making US businesses more competitive. That's because they're likely to conclude it will add to the nation's debt unless there are other revenue raising measures in the plan.

"They will lose a boatload of revenue that we can't afford to lose and far more than this team will offset by closing loopholes", Jared Bernstein, a former adviser to Vice President Joe Biden, told the Journal.

But on Sunday, Office of Management and Budget Director Mick Mulvaney appear to cast doubt on Mnuchin's statements, saying the White House still hadn't decided whether to pursue a long-term or short-term tax overhaul. "Deficits are certainly part of the discussion". After eight years of Obama's giving us growth of less than 2.0 percent a year, we badly need sustained, faster growth.

Republicans are pushing to pass tax-reform legislation under budget reconciliation to avoid a filibuster in the Senate.

As Republicans renew efforts to repeal and replace ObamaCare, President Trump is expected to outline his plan for tax reform, the next step in the Republican agenda. The question though is how big that effect would be.

Third, impose a low tax on the repatriation of foreign profits brought back to the United States.

Jens Weidmann, president of the Deutsche Bundesbank, said there was "very broad consensus at the meeting that we should work to continue the implementation" of financial reforms.

Holtz-Eakin, who also served in the Bush administration, was sceptical as well.

Boston University law professor Tamar Frankel, an expert in financial system regulation, said Dodd-Frank has not achieved the objective for which it was designed, which is to create consumer confidence in the banking industry. Republicans are split over issues such as a border adjustment tax on imports, while Democrats have vowed opposition until the president follows 40 years of tradition by making his own tax returns public. Note the words "tax reduction" in Trump's tweet. Beyond that, if his plan truly does not pay for itself, Trump may find it hard to find broad support in Congress. He said: "Such a big thing". "It can't begin to move through Congress. Members wouldn't vote for it".
