It is being called a planned assassination attempt.Saturday morning’s shooting of Arizona Congresswoman Gabrielle Giffords has sent shockwaves across the nation.Fellow congresswoman Chellie Pingree spoke out on Sunday about the Arizona shootings, as did Congressman Mike Michaud, and Senators Snowe and Collins.Pingree and representative Giffords served on the armed services committee together.Pingree says incidents like this are a reminder of the risks of being an elected official. She says a large part of the job is meeting with the public, and holding events: much like the one Giffords was attending in Tucson when she was shot. “I believe that civil discourse its much better in the home state of Maine, but I have held “congress in your corner” events where I’ve been sitting at a card table and people have been confrontational and angry and I do my best to engage in a dialogue with them. Like I said, you never know when its going to be the one person who is going to cross the line and endanger the lives around you, of innocent people and of your staff,” Said Maine Congresswoman Chellie Pingree.Pingree says members of congress held a conference call Saturday afternoon to discuss safety.Going forward, Representative Pingree says she will consider upping security measures, including adding local police.In September of 2008, Mike Michaud co-hosted a discussion with Giffords on mental health care for veterans. He called the shooting a national tragedy and an extremely sad day for our country.Senators Susan Collins and Olympia Snowe also expressed their shock and sadness to the tragedy, both saying their thoughts and prayers are with the families of the victims.
