A joint congressional field hearing today will address allegations of narcotic overprescribing practices and retaliatory behavior at Tomah Veterans Affairs Medical Center in Wisconsin.

Veterans and surviving family members will speak about the shocking abuse vets allegedly suffered at the VA facility.

Mike Tobin reported on "Happening Now" that lawmakers will hear from the family of Jason Simcackoski, a former Marine who died from a combination of drugs he was prescribed as an inpatient at the Tomah VA hospital.

They will also hear from the family of Thomas Baer, a Vietnam veteran who went to the emergency room at the facility in January, complaining of dizziness and trouble walking. Baer was forced to wait two-and-a-half hours in the waiting room where he had a stroke, ultimately suffering a second stroke and never making it home.

Tobin said that the primary allegation against the medical center is that the staff was thoughtless in overprescribing powerful medications.

It is also alleged that when problems were reported, whistleblowers were intimidated and problems were swept under the rug.

Tobin noted that Sen. Ron Johnson (R-WI) wants to hold someone accountable for the shocking abuses, but ultimately the function of the hearings is to get the testimony on the record.
