Iowa Congressman Leonard Boswell says changes have to be made in the treatment of veterans at Walter Reed Army Medical Center, and he believes things are on the way to getting better.

Boswell says he thinks a "sincere effort is going forth" and he believes the effort will move forward. Boswell, a Democrat and Vietnam veteran, says there’s more to it than treating physical wounds.

Boswell says: "We also must remember that not all wounds, not all wounds inflicted in combat are visible. The revelations at Walter Reed again remind me of the need to provide veterans with comprehensive screening and monitoring for risk factors of suicide."

Boswell says it’s more important than ever to pass the "Joshua Omvig Suicide Prevention Act," a bill Boswell is co-sponsoring to provide the suicide screening for Iowa veterans. Omvig was a soldier from Iowa who took his own life in December of 2005.
