Despite leading a somewhat frugal lifestyle, Hendricks has been known to donate to Republican political campaigns, including Rep. Marjorie Taylor Greene, who incorrectly blamed the tampon shortage on transgender people.

Hendricks is also a philanthropist, supporting WisconsinEye, Beloit College, Stateline Boys & Girls Club, and more.
