"Border security yes, tariffs no. Mexico is 3rd largest trading partner. Any tariff we can levy they can levy. Huge barrier to econ growth," Graham wrote in a tweet. "Simply put, any policy proposal which drives up costs of Corona, tequila, or margaritas is a big-time bad idea. Mucho Sad."

White House press secretary Sean Spicer did not give out specific details about the proposal he mentioned to reporters Thursday or explain how it would be implemented, but he said it could be included in a comprehensive tax reform package.

“We can do $10 billion a year and easily pay for the wall just through that mechanism alone. That’s really going to provide the funding,” Spicer told reporters aboard Air Force One.

Trump signed an executive order this week to get planning started on his campaign promise of the wall with Mexico.
