Embed code being stripped from posts for Admins

When I log in as a normal admin user of our multisite, the iframe and/or embed code gets stripped out of the post. Is there any solution for this? A plugin or a setting for our admins to give them the ability to add embed code.

I have read around on WP boards and it does not seem we are the only ones with this issue. I have given you support access to our site if you need it.

Thank you for any help or suggestions.
