House Republicans and Senate Republicans, including Sen. Ted Budd and prominent figures like Sen. Lindsey Graham and Sen. Rand Paul, demand answers from DHS Secretary Alejandro Mayorkas and FBI Director Christopher Wray regarding the apprehension and release of eight individuals from Tajikistan with suspected ISIS ties who crossed the southern border into the U.S. There are concerns about national security risks and failures in screening processes, with reports of individuals discussing bombs and possible ties to ISIS. The letters from the senators underscore the need to secure the border and prevent such incidents from recurring, reflecting broader worries about vulnerabilities in border security and immigration screening under the Biden administration.
