Alabama Republican Rep. Mike Rogers introduced legislation that would make undocumented immigrants pay for a border wall between the U.S. and Mexico.

The bill introduced Tuesday would impose a 2 percent fee on all wire transfers to the home country of undocumented immigrants, AL.com reported.

“This bill is simple — anyone who sends their money to countries that benefit from our porous borders and illegal immigration should be responsible for providing some of the funds needed to complete the wall,” Rogers said in a statement. 

“This bill keeps money in the American economy, and most importantly, it creates a funding stream to build the wall,” Rogers added.

During the presidential campaign, President Donald Trump repeatedly promised to build a wall on the U.S-Mexico border and famously said he would have Mexico pay for it.

Fellow Alabama Republican Rep. Mo Brooks tweeted support for Rogers’ bill and said he co-sponsored it.

I fully support @POTUS’ effort to build the wall & have Mexico pay for it. Glad to cosponsor @RepMikeRogersAL bill to fund construction. https://t.co/NXpfD8N90I
