Washington Democratic Rep. Marie Gluesenkamp Perez called out her fellow Democrat, Illinois Rep. Chuy García, for his sudden retirement plan, leaving his chief of staff as the only option in a position to succeed him. Garcia says he stepped down due to his health, his wife's worsening condition, and to help raise his grandchildren after the death of his daughter. CNN's Jake Tapper argues this incident shows US politics is often not about what's best for voters. | CNN
