The top tax-writing lawmaker in the House put on the hard sell Wednesday.
Ways and Means Chairman Kevin Brady on CNBC stood by the GOP's border tax on imports, which has been a lightning rod in the debate over how to reform U.S. corporate taxes.
"This will be in it. It will be designed and transitioned in a good way," Brady predicted on "Squawk Box" — a day after President Donald Trump, in his address to Congress, called for leveling the international playing field for American companies that find their exports heavily taxed by other countries.
Trump said: "Currently when we ship products out of America, many other countries make us pay very high tariffs and taxes. But when foreign companies ship their products into America, we charge them almost nothing."
But Brady argued the playing field can't be level with just a reduction in the federal corporate tax rate, which at 35 percent is among the highest around the world.
"It's like super-charging an old clunker of a car," he argued. "It can't compete and it can't drive along with the competitors we see today."
