What "Role" does a user need to add Google embed codes to their site?

I created a "Multisite" page and the google embed code that I put in their works; but when the "Member" goes to add it or even just edit it. The code gets stripped out.

Please help as this is holding up a 3 person team - on the clock - and the launch of our site...
