KANSAS CITY, Mo. -- There may be a problem with one of the most effective television ads being run by Democrat for U.S. Senate candidate Claire McCaskill. Her campaign can't prove it is true, KMBC's Micheal Mahoney reported.

The commercial is called "Josh." It is named after Kansas Citian Josh Lansdale, a medic who served and was wounded in Iraq.

"I returned from Iraq with a busted ankle and post-traumatic stress. It was six months before I could see a doctor," Lansdale said in the McCaskill ad.

Officials with the Veterans Administration Medical Center in Kansas City said Iraqi vets like Lansdale are priority veterans.

"We see them within 30 days of their entry into our system," said Jane Alley of the VA Medical Center.

Alley is a nurse and one of two people at the medical center who oversees new patients. Mahoney said it should be easy to check Lansdale's claims if he would produce his appointment schedule.

Mahoney reported that he went to one of the addresses for Lansdale, and for more than a week, Mahoney and the McCaskill campaign tried to contact Lansdale. Mahoney said he even asked Lansdale's mother to have him call KMBC.

In one brief telephone conversation, Lansdale praised the VA's mental health program, but he complained about how his ankle problem was treated. Mahoney said that indicates some sort of contact, but if, when and for how long cannot be determined.

"Politicians like Jim Talent don't have to wait six months for a doctor's appointment. Why should a veteran like me?" Lansdale asks in the McCaskill commercial.

"Are you aware of any Iraqi or Afghanistan veteran who has had to wait six months for their first appointment?" Mahoney asked Alley.

"I'm not aware of any. Like I said, I am not aware of any. But if there is someone out there with that experience, I need to know about that," Alley said.

Mahoney reported that since Lansdale would not meet with him to answer questions or take phone calls from the McCaskill campaign, he was unable to prove the accuracy of Lansdale's claim. The commercial is no longer airing on KMBC-TV.
