The Leadership Conference on Civil and Human Rights

This afternoon, police arrested approximately 100 disability rights advocates - many in wheelchairs - at a protest in front of the White House.

The protest, by the disability-rights group ADAPT, is in support of the recently-introduced Community Choice Act, which will give people with disabilities and older Americans who rely on Medicaid the choice to receive long-term care from community-based attendants as an alternative to nursing homes.

Also today, Rep. John Lewis, D. Ga., was one of five members of Congress who were arrested for civil disobedience outside the Sudanese embassy in Washington, D.C. The protesters were calling for Sudan's government to reverse a recent decision to expel international humanitarian agencies - such as Doctors Without Borders and Oxfam - from the Darfur region of Sudan.

Since 2003, more than 300,000 people have died in Darfur in a conflict between ethnic rebel groups and the national government. The United Nations reports that nearly 5 million people in the region currently rely on international humanitarian aid to survive.

And early this morning, Greenpeace activists hung a giant banner protesting global warming from a construction crane near the State Department. The message on the 600-square-foot banner, a photo of the planet earth and the phrase "too big to fail," was intended for government delegates from 17 countries who are attending the Major Economies Forum on Energy and Climate.
