An aide to Donald Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE on Wednesday fired back at Mark Zuckerberg after the Facebook founder apparently took a jab at the Republican presidential front-runner's rhetoric and immigration proposals.

"Well, you know, self-righteousness isn't very proactive. We can talk about taxes; we can talk about jobs and even immigration, but that doesn't really put food on the table and save lives," Trump spokeswoman Katrina Pierson said during an appearance on CNBC's "Squawk on the Street.""I think I'll take Mark Zuckerberg seriously when he gives up all of his private security, moves out of his posh neighborhood and comes live in a modest neighborhood near a border town, and then I'm sure his attitude would change," she added.The pushback came a day after Zuckerberg mentioned the "fearful voices calling for building walls" and blasted those trying to "divide people." While Zuckerberg didn't mention Trump by name in his remarks at a conference in San Francisco, his comments were tied to the businessman.

Pierson argued Wednesday that Trump's immigration proposals are aimed at "securing the life, liberty and property of the American citizens and the American worker" and ripped the Facebook executive for weighing in on politics.

"The CEOs in Silicon Valley should focus on innovation and jobs and their businesses, and let the politicians make the policies," Pierson said.

The aide acknowledged she could say the same thing about Trump but argued her boss is looking out for more than just himself.

"Yeah, but Donald Trump isn't the one that's saying we shouldn't build a wall and we should protect everyone else. That's the hypocrisy I'm talking about here," she responded.
