Tears in Rain

A young state senator hears about a mass shooting at a relatively close-by grade school where over 20 children are murdered. While the murderer is killed by the police, the fact that the children are dead and the extended family forever changed is cataclysmic. The senator goes on a rampage taking him to run for US senator and a lifelong attempt to pass an amendment for major gun reforms. When he wins the election, he learns how complex and personal congress can be and one thing leads to another.
