The Speaker and her house are irrelevant. Their actions are prettymuch just press releases
All they really have is an ineffective, benign cheerleading section for their political base.
They think they have power but one-half of the third branch of government does not have oversight over the another third branch, the Executive.
They can huff and puff all they want but they will blow nothing down.
With McConnell and Trump in the way, nothing of substance will make it out of the House into the Senate for a vote or on the president's desk to sign.
Pelosi and her herd of donkeys have an inflated view of their own self-importance.
