Trump threatens to double tariffs on Mexico, says 'they're sending migrants to US'

US President Trump has threatened to immediately double tariffs on Mexico unless its authorities stop “large migrant caravans advancing toward the southern US border”. Trump claimed foreign countries were sending unwanted individuals towards US, insisting that they “will not be accepted”. Trump contended that an “invasion” of US is resuming due to “perceived loss by the Republicans" in midterms.
