Protestors are upset at the size and scope of the federal government.

The event was headlined by the man known as "Joe the Plumber," a.k.a. Samuel Joseph Wurzelbacher.

Wurzelbacher became a political commentator last year after he questioned then-candidate Barack Obama about his tax plan during a presidential campaign stop.

Sen. John McCain then brought up "Joe the Plumber" several times during a presidential debate.



"It is our job to hold these politicians accountable to their actions. They can no longer treat us as a piggy bank. We need to say no," Wurzelbacher said at the rally.

The Denver rally followed another one held earlier in the day in Fort Collins.
