Former President Trump told a recent town hall he would, if elected, consider bringing back his zero tolerance policy that separated families at the border. 

Other 2024 GOP hopefuls and leaders are blaming the president.

Ambassador Nikki Haley told Fox News, "This falls on the president. This is absolute dereliction of duty." 

Vivek Ramaswamy added, "I blame the reckless abandonment that lies at the feet of Biden. Or, more precisely, his handlers."
