Answer:
Twenty-five years or older
Explanation:
According to the United States constitution, the age requirement to serve in the house of representatives is twenty-five years and above.
For a senator, the minimum age requirement is thirty years of age while an individual with desires, to serve as a congressman or woman, must meet the age requirement which is twenty-five. This is so because the U.S House of Representative is the closest to the citizens of the United States in terms of representation.
Besides attaining the age requirement which is twenty-five, he/she must be a citizen of the United States for seven years or more, and must primarily reside in the state they want to represent in congress etc.
