Senate Majority Leader Mitch McConnell (R-Ky.) is skeptical that Mexico will pay for the wall President Donald Trump promised to build along the U.S. border.

When Politico Playbook asked McConnell if he thought that Mexico would pay for the wall, he replied, “Uh, no.”

Having Mexico foot the bill became a rallying cry at Trump’s campaign events last year.

“And who’s going to pay for it?” he would ask. “Mexico!” the crowd would shriek in reply.

Yet it became clear just days into Trump’s presidency how unfeasible such a plan would be. Press secretary Sean Spicer floated the idea of raising taxes on imports from Mexico by 20 percent as part of a broader package to fund the wall’s construction in January. He quickly retracted the suggestion.

Mexico, meanwhile, has absolutely no intention of paying for the wall.
