Spicer said President Donald Trump has yet to make a final decision about how the U.S. will recoup the costs of his proposed border wall. Earlier Thursday that Trump wanted to slap a 20 percent tax on all imports from Mexico and predicted the tax would generate $10 billion a year.

He had told reporters on Air Force One that Trump has discussed the idea with congressional leaders and wanted to include the measure in a comprehensive tax reform package. But Trump's chief of staff Reince Priebus said later that the administration has "a buffet of options" to pay for the wall.

Importantly, Spicer said the White House was not ready to roll out any border tax at this time, and that it will will continue to have open line of communication with Mexico after Mexican President Enrique Pena Nieto canceled plans to meet with President Trump; Spicer says cancellation was mutual decision.
