The statement expresses a personal stance or opinion about supporting immigrants, which is not a verifiable factual claim that can be objectively proven true or false. As an opinion/declaration of values rather than an empirical assertion, it cannot be fact-checked as TRUE or FALSE in the traditional sense, though the speaker likely did make this statement.

The statement is a personal expression of political stance; since it is a direct quote from the speaker, it is factually accurate that he said he is on the side of Immigrant America.
