The head of the Federal Trade Commission’s Bureau of Competition told lawmakers Tuesday that the agency’s recent inquiries into Big Tech are part of an effort to reverse any possible errors in allowing mergers among the sector’s largest firms to move forward.

“We get things wrong, absolutely,” Bruce Hoffman, the director of the Bureau, testified before a subcommittee of the Senate Judiciary. “We’re never going to get things 100% right. But when we determine that we’re getting things wrong, we work really hard to try to fix that and get it right. And that’s what we’re trying to do now. I’m not saying it’s necessarily the case that we had all this wrong. I don’t know. That’s what we’re looking at.”
