Why would senate br tasked with overseeing the president while the house focuses on introducing bills relating to spending and taxing?

The Senate is tasked with overseeing the president to provide a check on executive power, ensuring that the president's actions align with the Constitution and the interests of the nation. This oversight role includes confirming presidential appointments and ratifying treaties. Meanwhile, the House of Representatives focuses on introducing bills related to spending and taxation because it is more directly accountable to the electorate, reflecting the immediate financial concerns of constituents. This division of responsibilities fosters a balance of power within the legislative branch.
