Tea party members are gathered in Phoenix for three days of meetings to push reforms and back Republicans.
Several speakers are scheduled to address the Tea Party Patriots policy summit at the Phoenix Convention Center.
Among the speakers scheduled to address the convention are former Minnesota Gov. Tim Pawlenty, U.S. Rep. Ron Paul, former U.S. Rep. John Shadegg and Sheriff Joe Arpaio.
The Arizona Republic reports an estimated 1,500 to 2,000 tea party members are expected to attend.
A Tea Party Patriots national coordinator says the group has a 40-year plan to instill in Americans the core values of fiscal responsibility, constitutionally limited government and free markets.
