MINNEAPOLIS (AP) - Some Minnesota Democrats are saying they won't let the shooting of a congresswoman in Arizona keep them from their constituents, but it might discourage those voters from coming to town halls.

Bill Harper, chief of staff to U.S. Rep. Betty McCollum of Minneapolis, says his office has heard from constituents for more than a year that they don't want to attend town hall meetings because of the tone.

Harper says those meetings are often disrupted by catcalls and shouting, a turnoff for constituents who want to hear what McCollum has to say if they don't agree with her.

U.S. Sen. Amy Klobuchar tells WCCO-AM that she'll attend each of the 13 public appearances she has scheduled in the next few days.

On Saturday, a gunman wounded Democrat U.S. Rep. Gabrielle Giffords and killed six people.
