Help with Visual Editor Adding Random CSS to Twitter Widget

Hi guys,

On our home page we have the html twitter widget inserted in the page. Whenever I update the page in the visual editor it adds some extra CSS code or something to the twitter widget which causes it to stop working. To fix it I have to manually go in every time and remove the code from the text editor and update the page again. Is there any way to isolate the html code or stop this from happening?

I've attached a screenshot of the code and the snippets that get added when I switch to a visual editor...
