I can provide information based on i am not an expert.
It seems there might be some confusion in your question. Kevin McCarthy was a Republican Congressman from California and not the Speaker of the House. The Speaker of the House is a leadership position in the U.S. House of Representatives, and I wouldn't be aware of them. I recommend checking more recent sources to get up-to-date information on Kevin McCarthy's actions and positions, especially if he has become Speaker of the House or had notable policy initiatives related to unity and fiscal responsibility.
