... In sum, in December 2023 speeches, Trump did call for mass deportations and emphasized that such migrants come from all over the world, using rhetoric that echoed past speeches. Furthermore, reporting confirms that there are indeed plans for a future Trump administration to build huge detention camps to hold migrants.
