Thousands of mostly Haitian migrants who crossed the southern border recently have not been tested for COVID-19 unless they have shown symptoms, according to a report. "Border Patrol sources working the Del Rio camp tell me that there is no COVID testing of migrants at the camp unless they are displaying obvious symptoms," Fox News correspondent Bill Melugin tweeted from Del Rio, Texas, on Thursday. "There are medical tents set up here where any migrants w/ health issues are taken into," Melugin said.
