Barney Frank, the Congressman from Massachusetts who made history by becoming the first openly gay member of Congress, has died at 86. Before he died, he shared his one last regret, and it involved President Donald Trump.

Barney Frank’s sister confirmed to NBC Boston that he passed away on Wednesday. Frank, who represented southern Massachusetts in the House for 32 years, became a very important person, not only to his voters but to people nationwide, as he was the first openly gay member of Congress.

Barney paved the way for other openly gay elected officials in the United States.
