Twitter Plugin that Creates a Post on your Blog

I’m working on a website for a local church – and their pastor maintains a twitter account to help bring new visitors to the website.

We’d like to set it up so that when he tweets, it automatically creates a post on WP – that way it keeps track of all his posts, and it allows visitors to comment etc.

I’ve yet to find a plugin that actually creates a post on WP – just ones that display the latest tweets or auto tweet your posts to wordpress.

Thanks.
