President Donald Trump likes to trash his opponents on Twitter, speaking to tens of millions of followers in short bursts. On Tuesday, he went after Google search results—for ”Trump news”—that showed mainstream news sites and their critical stories. He accused the company of “suppressing” conservative outlets.

Within hours, keeping Trump’s tirade alive a bit longer, Larry Kudlow, the White House chief economic adviser, told reporters that the administration is “taking a look” at whether Google search results should be regulated. Kudlow didn’t offer specifics, and one federal agency that might care—the Federal Trade Commission—declined to comment.
