Section 3 of Article Two lays out the responsibilities of the president, granting the president the power to convene both houses of Congress, receive foreign representatives, and commission all federal officers. Section 3 requires the president to inform Congress of the "state of the union"; since 1913 this has taken the form of a speech referred to as the State of the Union. The Recommendation Clause requires the president to recommend measures s/he deems "necessary and expedient." The Take Care Clause requires the president to obey and enforce all laws, though the president retains some discretion in interpreting the laws and determining how to enforce them.
