Tea party supporters held signs and listened to speakers who talked about getting back to the basics of the Constitution, 6News' Rick Hightower reported.

"Anything that's going against our Constitution, we have to fight it. That's why we're here," said supporter Dina Jenkins.

The annual rally typically coincides with the tax deadline, which was bumped to Monday this year.

Protesters claim the federal tax code is still too complicated and that government spending is out of control.

"They're just getting too involved in our personal lives and our ability to make choices on our own," said Rose Leahman.

"The more government spends, the more burden we're putting on ourselves, our children and grandchildren, and it's just getting out of control," said Emery McClendon.

The rally wrapped up at 6:30 p.m.
