Big tech firms will appear Thursday on Capitol Hill once again.
House Small Business Committee Chairwoman Nydia Velazquez invited Amazon, Alphabet's Google and Facebook to face questions from her committee on how the companies may be interfering with small businesses.
The hearing was originally reported last month by the Washington Post.
The companies have already face investigations from the House Antitrust Subcommittee, the Federal Trade Commission and the Justice Department.
In the hearing, Velazquez plans to home in on issues small businesses face when trying to compete with or promote themselves on the companies’ platforms.
The committee also plans a second panel with testimony from small businesses affected by the companies.
Amazon, Facebook and Google didn’t immediately respond to the Washington Post's requests for comment.
