Commerce Secretary Wilbur Ross said Tuesday that President Donald Trump did not endorse a border tax system in his joint address to Congress.

During his address, Trump said “When we ship products out of America, many other countries make us pay very high tariffs and taxes,” but when foreign companies ship products into the U.S., they pay “almost nothing.”

Ross told reporters after the address that Trump was talking only about the export tax inequity between the U.S. and other countries, but did not say how it would be remedied, Reuters reported.

“What he addressed was the issue that needs to be solved, which is there’s inequitable treatment of the U.S. Other countries have a value-added tax which they rebate on exports,” Ross said.

House Republicans have been pushing a tax to be levied against imports of about 20 percent. And in the past, Trump has said that a border adjustment tax could lead to job creation.
