Laravel Eloquent Where Created At

Im trying to query my NewsItem table for articles written in a given month / year.

I'm passing the url a GET variable

'/news?filter=true&month=January 2017'

In my controller I'm catching the variable and trying to run the query on my modal

if(Input::get('month')){
   $articles = NewsItem::where(DB::raw('created_at'),function($d){
        Carbon::parse($d->created_at)->format('F Y') = Input::get('month');
   })->get();
}; 

But I get the following error

FatalErrorException in NewsController.php line 28: Can't use method return value in write context

I'd like to know more about the function element within eloquent, are there any articles that will guide me in the right direction?
