Jeff Bezos, Chairman and CEO of Amazon, speaks at the George W. Bush Presidential Center's Forum on Leadership in Dallas, Texas, U.S., April 20, 2018.

President Donald Trump said his administration is looking into antitrust violations by Amazon, Facebook and Google parent Alphabet.

In a video interview with Axios' Jonathan Swan and Jim VandeHei that aired on Sunday, Trump said he's "not looking to hurt" the U.S. tech giants but is considering action.

"We are looking at [antitrust] very seriously," Trump said. "Look, that doesn't mean we're doing it, but we're certainly looking and I think most people surmise that, I would imagine."

Trump said others have also considered action against tech companies but a "previous administration" stopped that. "They were talking about this years ago. You know they were actually talking about this same subject — monopoly."
