Jenner, who as former Olympic champion Bruce Jenner in 2015 became the highest-profile American to transition to a woman, said she would decide in the next six months or so whether to run for the U.S. Senate in California.
Jenner told John Catsimatidis on his "CATS Roundtable" New York radio show on Sunday, that she is working with activist groups to improve the Republican Party's stance on lesbian, gay and transgender issues.
"Over the next six months or so I gotta find out where I can do a better job. Can I do a better job from the outside working the perimeter of the political scene, being open to talking to anybody, or are you better off from the inside?
"We are in the process of determining that. But yeah, I would look for a senatorial run," she said. Democratic U.S. Senator Dianne Feinstein is up for re-election in California in 2018.
