Dale Earnhardt Jr. joined NBC Sports Network’s “The Crossover” Thursday to discuss a variety of topics currently affecting the NASCAR Sprint Cup Series.

Earnhardt didn’t venture into critiquing the performance of NASCAR’s new Generation 6 car. He did question the timing of the National Rifle Association stepping up to sponsor the Sprint Cup race at Texas in April, though.

He made an additional promise at the end of the interview regarding his Twitter account, and made several plugs for sponsor AMP Energy Drink.
