ST. PAUL (AP) — When President Obama visits Minneapolis on Monday, one of the people most eager to see him will be a teenager who has turned into an unlikely advocate on gun issues.

Sami Rahamim  lost his father Reuven in September when an employee fired from Reuven's Minneapolis business went on a shooting rampage. Six people died before the gunman shot himself.

Sami is just 17, but other activists and politicians say he has quickly learned how to be an effective lobbyist. He has been at the Capitol nearly every day for a month, missing school to push for legislation that would boost background checks and tighten gun regulations.

Sami says he wants to see legislation passed that will make a "real positive difference" in cutting gun violence.
