Rep. Annie Kuster, a 68-year-old congresswoman from New Hampshire, is retiring to set a better example amid concerns about aging politicians.
Kuster believes that some colleagues stay in office for too long, and she wants to make room for younger people in Congress.
She states that she is not the best gladiator to serve as President-elect Donald Trump assumes office and Democrats face GOP control of Congress and the White House.
Kuster will be replaced by Maggie Goodlander, a 38-year-old Democrat who previously worked in the Department of Justice under President Joe Biden.
