It's official, Barack Obama has just sworn in as the 44th President of the United States of America in Washington DC. It was estimated that there are around 2 million people who attended the inauguaration. I watched the inauguration live, via CNN on the television. Rick Warren, Aretha Franklin, former President Bush [senior], former President Clinton and former President Carter were among the invited VIPs who attended. There was one VIP I didn't see though, Oprah.
