U.S. senators, led by Marco Rubio and Ted Cruz, have expressed significant security concerns regarding Canada's decision to increase the number of refugees from Gaza, warning that unvetted individuals with potential ties to Hamas could cross into the U.S. These lawmakers have urged the Department of Homeland Security to enhance border security measures, citing a recent uptick in suspected terrorists encountered at the Canada-U.S. border. In response, Canadian officials refuted these claims, asserting that Refugee Travel Documents are only issued to legitimate refugees after thorough assessments, and do not allow unrestricted travel to the U.S. The senators argue that the current situation poses a national security threat, particularly given the ongoing conflicts in Gaza and the potential for terrorist infiltration. Critics of the Trudeau government's refugee policies highlight that no other countries are accepting Gazan refugees, raising questions about the motives behind Canada's actions. The controversy reflects broader tensions in U.S.-Canada relations concerning immigration and border security.
