How can I rotate a sprite from an FlxScene?

[itsamedood]

I saw FlxScene and thought I would try it, but I'm not quite sure how to rotate a sprite that is inside the xml file.

Here's the xml file:

<?xml version="1.0" encoding="utf-8"?>

<scene width="1000" height="1000" bgColor="black" name="splash_screen" description="Plays on boot." version="1.0">
    <layer id="bg">
        <sprite graphic="assets/images/game/bg.png" x="320" y="120" width="2000" height="1500" />
    </layer>
    <layer id="main">
        <sprite graphic="assets/images/logos/me.png" x="384" y="-46" width="200" height="200" />
        <text id="meText" text="itsamedood" x="504" y="326.5" color="white" size="50" font="assets/fonts/hey_comic.ttf" />
    </layer>
</scene>

What I want is to rotate the sprite on the layer bg (line 5) by 0.03 every second using the update method, but how do I access the bg sprite from the xml file?
