Author-activist Chaz Bono is calling on his Twitter followers to back President Barack Obama's reelection campaign.

The 43-year-old Bono last month messaged his nearly 111,000 followers: “Happy 4th of July! As a proud American I support @BarackObama, and will do all I can to re-elect him. Please join me in this commitment.”

After Mitt Romney last week announced Wisconsin Rep. Paul Ryan as his pick for vice president, Bono messaged that the GOP ticket would be a step “backward” for gay rights and women.

“Romney's VP pick voted against equal pay for women and repeal of Don't Ask, Don't Tell. We can't go backward,” Bono tweeted.

On Tuesday, he added: “I have donate[d] my time and money to @BarackObama re-election, I hope you'll join me in doing the same. I remember how it was under Bush.”

“You[r] momma brought you up good :)” responded one follower.

A second disagreed: “Love you Chaz, but cannot join you on this.”
