Executive power is vested, with exceptions and qualifications, in the President. By law (Section 2.) the president becomes the Commander in Chief of the Army and Navy, Militia of several states when called into service, has power to make treaties and appointments to office "with the Advice and Consent of the Senate," receive Ambassadors and Public Ministers, and "take care that the laws be faithfully executed" (Section 3.) By using these words, the Constitution does not require the president to personally enforce the law; rather, officers subordinate to the president may perform such duties. The Constitution empowers the president to ensure the faithful execution of the laws made by Congress and approved by the President. Congress may itself terminate such appointments, by impeachment, and restrict the president. Bodies such as the War Claims Commission, the Interstate Commerce Commission and the Federal Trade Commission—all quasi-judicial—often have direct Congressional oversight.
David C. Vladeck (born June 6, 1951) is the former Director of the Bureau of Consumer Protection of the Federal Trade Commission, an independent agency of the United States government.

According to the Origination Clause of the United States Constitution, all bills for raising revenue, generally tax bills, must originate in the House of Representatives, similar to the Westminster system requirement that all money bills originate in the lower house. Traditionally, though, appropriation bills also originate in the House of Representatives. House appropriations bills begin with ``H.R. '', meaning`` House of Representatives''. In reference to revenue bills, the Constitution also states that the ``Senate may propose or concur with Amendments as on other Bills. ''As with revenue bills, the Senate and House each drafts and considers its own appropriation bill. The Senate then`` cuts - and - pastes,'' substituting the language of its version of a particular appropriation bill for the language of the House bill, then agrees to the bill as amended.
