Veterans Affairs Secretary Eric Shinseki said Sunday that the growing backlog in claims at the VA will end by 2015.

More than 600,000 claims are currently backlogged (defined as pending for more than 125 days) -- a sharp increase that has many veterans and members of Congress crying foul.

"No veteran should have to wait for claims like they are today. We have a fix for this," Shinseki said on CNN's "State of the Union." "We will end the backlog in 2015."
