His comments come a day after Axios published a leaked copy of a trade bill that would have the U.S. break with World Trade Organization rules.

Axios reports that under the bill the U.S. would elect to abandon the "most favored nation" principle, which says countries are not allowed to set different tariff rates for different countries outside of free trade agreements.

Trump was briefed on the drafted bill in May, according to the report.

"It is no secret that POTUS has had frustrations with the unfair imbalance of tariffs that put the U.S. at a disadvantage. He has asked his team to develop ideas to remedy this situation and create incentives for countries to lower their tariffs. The current system gives the U.S. no leverage and other countries no incentive," White House spokeswoman Lindsay Walters told Axios

Scaramucci's comments come just days after he said that Trump's trade wars may be going too far.

On Sunday, Canada retaliated against Trump's steel and aluminum tariffs by imposing tariffs on about $13 billion worth of U.S. exports.
