Protesters were arrested trying to occupy Sen. Lieberman's office Tuesdayon Capitol Hill.

Washington (CNN) - Police arrested six demonstrators Tuesday inside the Capitol Hill office of Sen. Joe Lieberman (I-Connecticut), after a group protesting his views on health-care legislation refused to leave.

Lieberman was not there at the time.

A group calling itself the "Mobilization for Health Care for All" littered the floor and hallway with symbolic "money," and said campaign donations to Lieberman by the insurance industry have affected his judgment of health-care legislation.

The group is upset that Lieberman refuses to support the "public option," that they believe would reduce the number of people without health-care insurance.

Lieberman later denied that his view has been affected by political support from the insurance industry. "I'm for health insurance reform," he told CNN, "I don't want however, as part of that to create another large, government-run insurance company. We can't afford it, we're already deeply in debt, the taxpayers can't afford it, our government can't afford it."

But one of the protesters, Sheila Dvorak, said "insurance companies bribe our elected officials." She was among those arrested and charged with unlawful entry, according to U.S. Capitol Police Sgt. Kimberly Schneider.

While only about a dozen demonstrators showed up for the protest, they were determined not to leave until they could directly ask the senator to reject future financial support from the insurance industry.

Lieberman had departed for a hearing about ten minutes before demonstrators began to assemble outside his office.

Staffers offered to convey their concerns, but the protesters then started singing and chanting, prompting a call to police.

Reached outside a hearing room, Lieberman told CNN, "Everybody has a right to express their point of view, I much prefer to have a dialogue, of course. But I think, some of these folks come in to get arrested, that's their right too."
