American Psychological Association citation style is commonly used in the social sciences. APA style requires you to cite quoted, paraphrased or summarized sources within your paper, and also to provide a list of full bibliographic references at the end of your paper. According to the APA Style Blog, the proper format for citing a presidential speech depends on the type of source the speech was published in.
List the last name of the author of your source, followed by a comma, followed by the year in which the source was published for an in-text citation. Your in-text citation should be enclosed in parentheses. For example:
Position your in-text citation so that it directly follows the paraphrased or quoted source, but appears before any concluding punctuation such as a period. For example:
Reagan once again avoided specific commitment in August of that year, stating in a speech at Columbia University that "what needs to be done will be done" (Smith, 2009).
Organize your full bibliographic reference in the format appropriate to the type of source you are using. For example, if you were quoting the speech from a published book, your reference should be arranged as follows:
Author's Last Name, First Initial. (Year of Book's Publication). Title of book in italics. City of Publication: Name of Publisher.
Smith, F. (2009). Reagan's tenure. Ithaca, NY: Presidential Press.
