What will think and do Obama if Ebola will come to Whitehouse - in any way - for example from foreign leaders staff members
Not exactly sure what you are trying to say, but I'll give it a go. There is 0 chance a foreign leader gets close to Obama if there is any chance they make have Ebola. People seem to forget, that Ebola isn't easy to transmit to other people. The whole Ebola scare has been blown out of proportion.
Now, if it did happen, you can guarantee that Obama would get the best treatment possible. With proper medical treatment early enough, Ebola isn't fatal.
