"I won't comment on the breaking up, of whether it's that or Amazon or Facebook," Trump said in an with Bloomberg News. "As you know, many people think it is a very antitrust situation, the three of them. But I just, I won't comment on that."

He charged the firms with exhibiting a bias against conservatives.

Trump has accused the tech giants of being anti-conservative and for allegedly stifling conservative speech.

He tweeted on Tuesday that Google News was biased against conservatives and said, "This is a very serious situation-will be addressed!" 

He later said that Google, as well as Facebook and Twitter, were "treading on very, very troubled territory."

Trump walked back his threats of regulation though on Wednesday.

"Not regulation. We want fairness," Trump said.
