Immigrants waiting for their Immigration Court hearings under the "Remain in Mexico" MPP protocols have been rapidly increasing in number. Case-by-case court records obtained by the Transactional Records Access Clearinghouse (TRAC) at Syracuse University show that during July a total of 11,804 immigrants were sent back to Mexico to await their MPP hearings. This is up from 5,161 during May and 5,883 in June.
