Watch: John McCain's concession speech video
John McCain addresses the 7,000 supporters who had crammed into the Biltmore Hotel and congratulates Barack Obama on his election victory.
"Senator Obama and I have had and argued our differences," he said. "No doubt those differences remain. But these are difficult times for our country. And I pledge to him tonight that I will help him lead us through the many challenges that we may face."
"I urge all Americans to join me in not just congratulating him, but in offering our next president our goodwill and encouragement in finding ways to come together, to find the necessary compromises to settle our differences, to help restore our prosperity, defend our security in a dangerous world and leave our children and grandchildren in a stronger better country than we inherited."
