The push to abolish ICE grew among Democrats last week following Alexandria Ocasio-Cortez's upset defeat of Rep. Joseph Crowley in a Democratic primary in New York. Ocasio-Cortez has called for abolishing ICE, with her win over the fourth-ranking House Democrat sending reverberations through the party.

ICE received increased scrutiny recently following backlash over the administration's "zero tolerance" immigration policy at the border, which led to the separation and detention of thousands of children away from their parents while the adults face prosecution for illegally entering the U.S.

Trump signed an executive order to end the practice last month, and has ripped calls from Democrats to abolish ICE, predicting this weekend that lawmakers who back the effort are "going to get beaten so badly."

"I am just appalled by how this administration has been talking about immigrants," Klobuchar said Sunday while calling for comprehensive immigration reform. "They don't diminish America, they are America."
