Former U.S. Ambassador to the U.N. Nikki Haley has another way of explaining why Vice President Kamala Harris is fearful of visiting the southern border.

Speaking on Fox News on Tuesday, June 8, Haley criticized Harris for her “embarrassing” approach to the border crisis, lamenting that how can she fix the problem if she cannot see it.

“I don’t know what the problem is. Clearly, she is fearful, but Kamala Harris was given one job — one job — and that was to deal with the border, and any leader knows you can’t fix what you can’t see,” Haley said.

But “she hasn’t been on the ground, she hasn’t talked to Border Patrol—she doesn’t know what is happening there,” Haley said of Harris, calling it “embarrassing.”

The former ambassador to the U.N. made the remarks as the vice president has refused to travel to the U.S.-Mexico border for nearly 80 days since President Joe Biden put her in charge of his administration’s response to the immigration issues in March. She instead opted to visit Guatemala and Mexico to seek to address the “root causes” of the border crisis.

“I appreciate that she’s going to Guatemala. I appreciate she’s going to Mexico. You know why?” Because both of those leaders say that the Biden administration is the reason they are having all these problems at the border,” Haley said on Fox News.

Haley then gave her opinion on Harris’s fear to visit the U.S. border despite the ongoing crisis there.

“I don’t know what her fear is at the border, but clearly, she has one,” Haley said. “And I don’t know what Biden’s fear of the border is, but he has one. What I will call it is flat-out denial. They think that if they don’t go, it won’t be real. It’s very real.”

The former diplomat also slammed Harris’s double standards toward the immigrants from Central America.

“This is the same woman that literally tweeted out, ‘Come one come all, we are open for everyone,’” the former diplomat said. “And so now she’s going to say do not come. You know it says do not come? When you show up at the border, and you really have actions speak louder than words.”

During a press conference with Guatemalan President Alejandro Giammattei on Monday, June 7, Harris said that the Biden administration’s goal is “to help Guatemalans find hope at home.”

“I want to be clear to folks in the region who are thinking about making that dangerous trek to the United States-Mexico border: Do not come. Do not come,” she said. “I believe if you come to our border, you will be turned back.”
