President Trump said Thursday that the thousands of migrants heading for the southern U.S.-Mexico border are not “legitimate asylum seekers.”

“The government of Mexico has generously offered asylum, jobs, education and medical care for people within the caravan, but many members of the caravan have refused these offers, which demonstrate that these migrants are not legitimate asylum seekers,” Trump said at the White House on Thursday. “They are not looking for protection because if they were, they would be able to get it from Mexico.”
