He was acquitted at trial and his impeachment trial was not heard before the full Senate, this is why Hastings serves in the House today.
To this day, he still tries to play the victim card due to his color, so there is a lot of misinformation around. The House could have refused to seat him when he was elected just five years later, but he was swept in on the Clinton coat tails and the jackass party had a super majority similar to now.
