Amy Kremer, the chairman of the Tea Party Express, announced Friday that she was resigning her post heading the influential conservative group effective immediately.

“This has been a really difficult decision for me, but the time has come for me to leave Tea Party Express,” said Kremer in a post on Facebook.

“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,” she added. “So as we move into this election cycle, I think the time is right.”

Kremer said she was “proud” of the work Tea Party Express had done and vowed that she would remain involved in conservative politics, focusing her attention on key Senate primaries ahead of November’s midterm elections.

“As one of the only remaining members of the original tour, Tea Party Express has been a huge part of my life and I am proud of the historic work we accomplished -- like partnering with CNN to host the first ever Tea Party Presidential Debate and electing conservatives such as Senators Mike Lee and Ted Cruz to Congress,” she wrote.

“While I can’t give the specifics yet, my new projects will keep me working in that movement,” said Kremer.

“While I may no longer be on a bus, I will definitely be on the ground, continuing my work in the movement and for the conservative cause. I’m excited about engaging in competitive Senate primaries and supporting fiscal conservatives in the coming weeks,” she said.

According to CNN, which first reported her move, Kremer will be working with businessman Matt Bevin, who is challenging Senate Minority Leader Mitch McConnell, R-Ky.
