Former Senate aide pleads guilty to sexual abuse

WASHINGTON -- A former Democratic Senate aide has pleaded guilty to sexually abusing two women who were under the influence of drugs or alcohol.

The Washington Post reports that 37-year-old Donny Ray Williams pleaded guilty Tuesday in D.C. Superior Court. Williams had served as a staff director for the Senate Homeland Security and Governmental Affairs subcommittee.

Both of the assaults occurred in 2010. Prosecutors say Williams invited a colleague to his apartment, where he spiked her drink with a sleep aid and raped the woman while she was asleep.

A month later, prosecutors say Williams gave a woman alcoholic beverages and had sexual contact with her when she was too drunk to consent.

Prosecutors plan to seek a suspended prison term and five years of supervised probation.
