Obama is bringing Attorney General Eric Holder, Defense Secretary Chuck Hagel, Education Secretary Arnie Duncan and Health and Human Services Secretary Kathleen Sibelius to the Oval Office on Wednesday to press them to work on the problem. Then he plans to join an ongoing meeting of his Council on Women and Girls attended by more Cabinet members in the East Room, where he is to sign the memorandum creating the task force. Vice President Joe Biden, who wrote the Violence Against Women Act and has led other efforts to reduce sexual assault, also plans to attend.
