Donald Trump’s most famous campaign proposal was that he would build a wall along the Southern border and get Mexico to pay for it.

The left said it couldn’t be done.

But the Trump administration has unveiled a proposal which will have Mexico funding the construction for wall.

Attorney General Jeff Sessions appeared on ABC’s This Week and was questioned about the funding.

He stated that erroneous tax credits which have mostly gone to Mexicans would pay for the wall.

Politico reports:

“Speaking on ABC’s “This Week,” Sessions weighed in on the fight over funding for the wall, which is becoming part of the high-stakes negotiations between the White House and Congress over keeping the government funded after Friday.

“We’re going to get paid for it one way or the other,” Sessions said of the wall. “I know there’s $4 billion a year in excess payments, according to the Department of the Treasury’s own inspector general several years ago, that are going to payments to people — tax credits that they shouldn’t get. Now, these are mostly Mexicans. And those kind of things add up — $4 billion a year for 10 years is $40 billion.

“There are a lot of ways we can find money to help pay for this.”

Presumably the report that Sessions was citing was a July 2011 report by the Treasury inspector general for tax administration that said individuals who are not authorized to work in the U.S. have been paid $4.2 billion in refundable tax credits. But it did not mention Mexicans or any other nationalities.”

Some in the so-called “mainstream” media have questioned why the wall is necessary.

Illegal border crossings are down 67 percent since Trump took office.

His crackdown on illegal immigration has clearly had an effect in discouraging individuals from trying to enter America illegally.

Trump responded on Twitter that the wall was vital to stopping the flow of illegal drugs from entering America.

Trump has also indicated he is willing to stage the fight to begin funding construction of the wall in September when the government must pass a 2018 fiscal year budget.

But the recent announcement by Attorney General Sessions shows the administration is serious about building the wall and developing a plan to have Mexico pay for it.
