Florida Civics Literacy (FCLE) Practice Exam

When the US President and Vice President are unable to serve, the Speaker of the House steps in as acting President. This is outlined in the Presidential Succession Act of 1947. The Secretary of State, President Pro Tempore of the Senate, and Chief Justice of the Supreme Court are all in the line of succession, but they would only become acting President if the Speaker of the House was also unable to serve. Therefore, options A, B, and D are incorrect choices.
