Michelle Obamas Trip To Africa Cost $800,000 Tax Payer Dollars. Was It Appropriate?

Michelle visited South Africa and brought along her two daughters.her mother and two of her brothers children. They visited museums, and Landmarks and even went on a Safari. I understand that she was there to promote youth leadership,education and health but considering the current economic difficulties America is struggling with it is appropriate for her to spend $800,000 of hard earned American tax dollars on a tax payer funded vacation for her Family and friends? During these hard times most Americans can't even afford a bungalow at the shore for a weeks vacation. I don't think the Trip was appropriate. If she had to visit Africa why did she have to drag her children friends and relatives along at tax payer expense? Im starting to see why her nickname is "Moochelle"
