What do you think of reports that Obama's trip to Africa could cost tens of millions of dollars?

I saw it on the news, honestly I haven’t looked much into it. Here’s the link to Washington Post article:

The article talks about support vehicles, snipers, etc. I’m sure there are many other articles available if you google.

I chose Washington Post because I figured they might be somewhat objective.
