Dozens of protestors, including actor Noah Wyle, were arrested Monday afternoon following a demonstration in the Cannon House office building.

Capitol Police spokeswoman Lt. Kimberly Schneider confirmed that officers arrested Wyle and 75 others for unlawful conduct, demonstrating in a Capitol building.

Hundreds of people reportedly filled the building’s rotunda Monday, demonstrating against cuts in Medicaid proposed by Republican House leadership. Many of the protesters were members of ADAPT, a grass-roots disability rights organization.

The demonstration was part of a three-day series of actions Monday through Wednesday that aim to “highlight the failure of the federal government to protect community based services for very low income people with disabilities who rely on Medicaid,” according to an ADAPT statement.

Wyle, an Emmy and Golden Globe-nominated actor for his work on the television series "ER," was slated to join hundreds of disability rights activists in the 7th annual ADAPT Fun Run for Disability Rights Monday in Upper Senate Park to raise funds for the organization’s campaign to preserve Medicaid.

A member of ADAPT’s leadership confirmed Wyle’s support of and participation in Monday’s protest, and subsequent arrest.
