A former Mexican president had some tough words when asked about GOP candidate Donald Trump's much-touted plan to build a border wall that he says will be paid for by Mexico, NBC News reported.
"We are not going to pay any single cent for such a stupid wall! And it's going to be completely useless," said former Mexican president Felipe Calderón when asked about this at the AmCham Egypt for Business Conference on Sunday.
Calderón had harsh words about the Republican presidential race during his conversation with CNBC's Hadley Gamble, saying it was "incredible" that quite an "admirable society" like the U.S. had candidates like Trump.
Trump has made border issues and immigration one of the key centerpieces of his campaign, saying on the day he announced he was running that Mexico was sending "rapists" and "criminals."
