Rep. Ken Buck (R-Colo.), the lead Republican on the House Judiciary antitrust subcommittee, will stop accepting donations from Google, Facebook and Amazon, he said Wednesday.

Why it matters: Buck (R-Co.) is declining Big Tech donations as regulatory scrutiny on tech companies heats up in Washington.

• Generally tech companies give to individual candidates through their political action committees. Many of those PACs are currently on pause following the Capitol riots.

Flashback: Buck for Colorado received $2,500 each from Google LLC Netpac and Amazon Pac in 2020, according to Federal Election Commission records.

What they're saying: "As the lead Republican on the antitrust subcommittee working to hold Big Tech accountable for their anticompetitive and monopolistic behavior, I cannot continue to accept campaign donations from Facebook, Google, or Amazon," Buck said.

• The antitrust subcommittee is scrutinizing Apple for its control of the App Store as well, but Apple does not have a political action committee.
• Buck and Rep. David Cicilline (D-R.I.), the chairman of the subcommittee, have told Axios they expect to roll out antitrust bills targeting the tech industry soon.

What to watch: Whether other legislators follow Buck's lead.
