AI response to question: can the Vice President acting as president of senate change filibuster rules?

"Yes, the Vice President, acting as the President of the Senate, has the constitutional authority to influence filibuster rules, primarily by making rulings that allow the Senate to change procedures with a simple majority rather than the typical 60-vote threshold. This authority is exercised by interpreting or challenging existing rules as unconstitutional, a power used historically to eliminate filibusters for executive and judicial nominees."
