PHOENIX (KSAZ) - It's an idea that has been at the center of his Presidential campaign, one that has drawn both widespread criticism and widespread support.
Donald Trump revealed earlier Tuesday his plans to force Mexico to pay for the wall that he wants to build along the border. Trump is threatening to cut off the flow of billions of dollars people send back to family and friends in Mexico.
More than 24 billion dollars flow into Mexico from the United States annually. Trump says he would change that unless the Mexican government agreed to pay for a border wall he would block undocumented immigrants from sending money back home.
Every month Miguel Hernandez sends a few hundred dollars from Phoenix back to his family in Mexico.
"I support family here, and support family in Mexico too," said Miguel Hernandez.
Donald Trump wants to cut off billions of dollars in remittances, a safety net for many families in Mexico.
Trump says if the Mexican Government doesn't agree to pay 10 to 15 billion for a border wall he would block remittances specifically from undocumented immigrants in the USA.
Arizona Banker's Association President Paul Hickman says the idea puts US banks in a tricky position to determine citizenship status.
"Once again we are putting banks in the business of police and law enforcement which is not what we do," said Paul Hickman.
Former Arizona Governor Jan Brewer supports Trump's proposal.
"Donald Trump is offering solutions to something the President has had the opportunity for 7 1/2 years to address, and I believe that the Americans that are here realizing that those millions billions of dollars are going south of the border to boost up their economy are American dollars that could be left in the United States to boost our economy," said Jan Brewer during an interview with FOX News.
Still critics of the plan say it would have the opposite effect by driving up illegal immigration.
"I think if he stopped being able to send money to Mexico lot of people will come here looking for money," said Hernandez.
