TULSA, OK -- Thousands will gather at Tulsa's Expo Square at 6 p.m. Thursday for what is expected to be the largest Tea Party gathering in Oklahoma history.

Thursday's Tax Day Tea Party will be sponsored by the USA Patriots, and supported by AM 740 and FM 102.3 NewsTalk KRMG.  The gates will open at 4 p.m.

Oklahoma State Senator and Republican candidate for Governor Randy Brogdon will headline the event.

Special guests also include Vision America founder Dr. Rick Scarborough, federal prosecutor Vicki Behenna, Broken Arrow "American Idol" contestant Alaina Whitaker and several other exciting public figures and elected leaders.

"The American people are paying attention now," says USA Patriots founder Chris Kurtz, "When the government doesn't listen, we notice. When they don't respond in a way that represents the majority, we notice and we will rally and we will act!"

More than 1,000 people took to the lawn outside the state Capitol Wednesday night for a tea party rally as speakers lashed out at a federal government they say is trampling on the individual liberties of citizens.

Waving flags that read "Don't Tread on Me" and holding signs criticizing federal spending, the group packed the north lawn Wednesday night.

Between speakers, organizers offered prayers and played patriotic music.

Conservative Oklahoma City radio host Mark Shannon urged the group to harness their energy into making a difference in November's elections.
