This week, experts rained fire on Donald Trump's plan to build a wall between the U.S. and Mexico.

Several months ago, Trump released a day-by-day plan on his election website detailing what his presidency would do to compel Mexico to pay for the wall.

On day one, Trump said he would propose regulations that bar persons from wiring money outside the United States without proof of "lawful presence in the United States."

Trump says that these remittances to Mexico serve as "de facto welfare" for the poor families living there. By day three, if Mexico refused to pay for the wall, Trump's proposal would go into effect.

But this might not be a problem for illegal immigrants.

Nestor Rodriguez, a University of Texas sociology professor who studies immigrants, told Politifact that "Someone else with legal status may send the money to Mexico on behalf of the undocumented immigrant, or send money in cash with people traveling."

President Obama believes stopping these remittances is an impossible task, too.

"The notion that we're going to track every Western Union bit of money that's being sent to Mexico, good luck with that," Obama said.

If Trump's logistics did pan out, the president says it would only make things worse.

"Then we've got the issues with regard to implications for the Mexican economy, which in turn, if it's collapsing, will actually send more immigrants north because they can't find jobs back in Mexico," Obama said.

Trump's plan also calls for increasing fees for visas and border crossing cards, as well as enforcing trade tariffs. Trump points to the deficit between Mexico and the United States, and how reversing that deficit would help pay for the wall, too.

"Trump's connection of the trade deficit with a Mexican border fence is just nonsense," Alex Nowrasteh, an expert on immigration from the Cato Institute, told Politifact in an earlier article.

"Just because the Mexican economy has a trade surplus relative to the United States doesn't mean the Mexican government has the resources to build a border wall. It would be like me threatening my neighbor to build a new fence or else I'll stop shopping at Walmart."
