“This has been a really difficult decision for me, but the time has come for me to leave the Tea Party Express,” Ms. Kremer wrote, on her Facebook page.
“I’ve wanted to move in a different direction for a while, but also wanted to make sure that any change I make was also a positive change for the conservative movement. So as we move into this election cycle, I think the time is right.”
The Tea Party Express formed in 2009, and rose to national prominence with an active political presence that included a bus tour around the country.
Her resignation kicks in immediately.
