Senate Majority Leader Mitch McConnell (R., Ky.) said Friday that he will not be intimidated by protesters who confront him calling for the abolition of U.S. Immigration and Customs Enforcement.

Demonstrators shouting “abolish ICE” confronted McConnell as he was leaving a restaurant in Kentucky on Saturday.

The incident came after protesters associated with the Democratic Socialists of America harassed Republicans and other government officials over the Trump administration’s immigration policies in recent weeks, while some Democrats have called for abolishing ICE. McConnell dismissed their demands for “open borders” and said it is worrisome that some Democratic senators would entertain the notion.

“Let’s understand what they are suggesting here: Getting rid ICE, the Immigration and Customs Enforcement, and having no one at all patrol the borders,” he said at a press conference. “What I worry about is that that point of view seems to be moving into the United States Senate.”
