(CNN) - A leader in the Tea Party movement will take part in what's being billed as the "first annual national convention" for the Coffee Party.
Billed by many as a progressive answer to the much larger conservative Tea Party movement, the Coffee Party was born on Facebook at the beginning of the year. The group became popular online - it has nearly 300,000 Facebook fans - and has held numerous gatherings across the country this year.
In an email release, the group announced that its convention will be held September 24-26 in Louisville, Kentucky, and will feature a panel discussion of transpartisan issues. Among those on the panel will be Tea Party Express chairperson Amy Kremer. The Tea Party Express is one of the best known national Tea Party organizations.
"Earlier this year, we declined most of the invitations we received to appear with Tea Party leaders," said Coffee Party co-founder Annabel Park. "We felt the Coffee Party needed to go through an internal process first. Now that we've done that, we are eager to engage with the Tea Party, and help to move America's civic discourse beyond the narrow confines of partisanship."
The Tea Party Express confirmed Kremer's involvement in the convention.
"We are certainly always willing to have a conversation about the goals of the tea party movement, and find opportunities with work with others to help achieve those goals," says Kremer in a statement. "As a true non-partisan movement, we are happy to engage with all those who are concerned about the troubling state of our economy, and discuss why the tea party movement is so important. I look forward to representing the movement as just one of millions of concerned citizens who are also worried about the direction of the country."
