The Constitution directs the Senate to choose a president pro tempore—Latin for "for the time being"—to preside when the Vice President is unavailable. The Senate elects this officer by resolution, typically unanimous consent, with the position traditionally going to the majority party's most senior member.
The president pro tempore rules on procedural points, administers oaths, signs legislation, and co-presides at joint sessions with the House Speaker. Under the Presidential Succession Act of 1947, the officer ranks third in line for the presidency after the Vice President and House Speaker.
The 25th Amendment requires the president pro tempore and Speaker to receive declarations when the President becomes unable to perform duties or resumes them. Unlike the Vice President, the president pro tempore cannot cast tie-breaking votes. The position carries full-time security detail due to its succession role and receives various reports including War Powers Act notifications.
The President Pro Tempore is third in the presidential line of succession. Understanding this role matters because it shows how Congress is organized and who would assume the presidency if both the President and Vice President become unable to serve.
People often think the President Pro Tempore is as powerful as the Vice President. In practice, the role is mostly ceremonial—presiding over the Senate when the VP is absent—but carries significant succession implications.
