Update to this story.

Via Fox News:

While Donald Trump doubled down this week on his vow to make Mexico pay for his proposed southern border wall, his campaign is reported to be weighing options that don’t necessarily involve the seemingly far-fetched scenario of the Mexican government handing America a great, big check.

LifeZette first reported that the Republican presidential nominee and his top advisers are looking at using assets seized from drug cartels and other traffickers. This reportedly could involve establishing a “joint border security fund” — holding seized assets from crackdowns on both sides of the border – for border construction and maintenance.

Trump, asked Thursday by Fox News about the report, did not deny the option is on the table.

“There are many ways that they can pay for the wall,” Trump said, calling it a “negotiation.”

But he again insisted, “The United States will not be paying for the wall. Mexico will be paying for the wall.”
