(CNN) Bruce Jenner didn't just come out as a transgender woman Friday night — he also came out as a Republican.

In a two-hour special aired on ABC, Jenner, 65, sat down with Diane Sawyer and revealed what has been speculated by the public for months. But he shared another fact that sent waves through the political community, telling Sawyer he's a Republican, too.

Jenner is most known for his Olympian days and later his marriage to Kris Kardashian, making him the stepfather to Kim Kardashian and father to Kendall Jenner and Kylie Jenner. He re-entered the spotlight after becoming a regular on the family's reality TV show "Keeping up with the Kardashians."

The conversation about his political stance began when Sawyer asked him his thoughts about Barack Obama becoming the first president to use the word "transgender" in his 2015 State of the Union.
