In fight over veterans benefits, McCain strikes back at Obama with blistering statement:
"As he always does, he prefers impugning the motives of his opponent, and exploiting a thoughtful difference of opinion to advance his own ambitions...."
"Unlike Senator Obama, my admiration, respect and deep gratitude for America's veterans is something more than a convenient campaign pledge."
Obama and other Democrats have criticized McCain's opposition to bill boosting benefits for veterans.
