Another big-name Hollywood actress is coming to Capitol Hill as part of a year-long push to pass new legislation expanding access to mental health care.

Glenn Close will join senators Wednesday in support of the Excellence in Mental Health Act, a measure co-sponsored by Sens. Debbie Stabenow (D-Mich.) and Roy Blunt (R-Mo.) that is aimed at strengthening the nation’s fragmented mental health-care system and improving access at the community level by allowing smaller community mental health centers to bill Medicaid for their services if they meet certain criteria.

Close is a longtime advocate for improving mental health care services and is a founder of Bring Change 2 Mind, a group pushing to end discrimination against people with mental illness. She's joining a campaign to pass the legislation, which was drafted in the wake of last year's shooting massacre at Sandy Hook Elementary School in Newtown, Conn.
