"Because of the Trump Administrations actions, Border crossings are at a still UNACCEPTABLE 46 year low. Stop drugs!" he tweeted.

Trump also said in his tweet the migrant caravan moving toward the US-Mexico border has "largely broken up thanks to the strong immigration laws of Mexico and their willingness to use them so as not to cause a giant scene at our Border."
