Pete Buttigieg has been one of Joe Biden's most effective attack dogs, including viral appearances on Fox News, where he could always be counted on to take the fight to the right.

Now, Biden's former rival for the Democratic nomination for president will be his nominee for Secretary of Transportation. It will be Buttigieg's first federal position, and if he is approved by the Senate, he will become the first LGBTQ person to achieve that distinction at the Cabinet level.

Three cheers for progress.
