McCaskill says she wants to improve conditions at hospitals by simplifying paperwork for recovering soldiers and improving standards at outpatient facilities. But some military families against this war want her to do more to end it.

Military mom Valarie Fletcher was among more than a dozen anti-war demonstrators trying to send a message to the senator inside a meeting with supporters. Fletcher voted for McCaskill in November but now says she regrets her vote.

"(McCaskill's) not going far enough," she said.

Fletcher's son has been in Iraq for about five months and he just got word that his tour is going to be extended. So, for her, this war is not political, it's personal.

Fletcher, like other anti-war protesters, wants McCaskill to help cut off funding for the military, something McCaskill refuses to do and calls dangerous.

"When you try to take money away that's been asked for, they get to decide where the money is spent that they get. And you have no assurances that they are in fact going to pull back troops in Iraq. They might just pull back treatment for outpatient units at military hospitals around the country," McCaskill said.

Instead, McCaskill says, she's looking at trying to limit the number of troops that are sent to Iraq .
