"To have a contentious conversation and name-call a country or the Prime minister of a country that's one of our greatest allies in Asia is foolish," said the Democratic senator from Virginia, who was Hillary Clinton's running mate in 2016. "To suggest to the President of Mexico we may have to send US troops into Mexico is foolish.
