(KMOV)-- Congressman Lacy Clay reacted to the mass shooting in Arizona Saturday.
Clay calls Gabrielle Giffords a friend and a colleague who loves her job.
The congressman says if violence becomes a part of politics, it means public discourse has gone too far.
Members of Congress were briefed on security measures hours after the shooting.
Clay did not give many details, but says all of Congress was told to take precaution and watch their backs. He says he will not be deterred from doing his job.
