White House economic adviser Larry Kudlow said Tuesday that President Donald Trump is considering new regulations on Google’s search engine to address his concern that it turns up too many stories that are critical of him.

Pressed by reporters at the White House on Tuesday about a tweet the president wrote criticizing Google’s search engine as “rigged,” the director of Trump’s National Economic Council said the administration is “taking a look” at federal regulations for the company.

“We’ll let you know,” he said.

Earlier, Trump expressed frustration on Twitter that when Americans type “Trump News” into the search engine, it generates mostly negative news about him while conservative media is “shut out.”
