More than 80 lawmakers have called on the Obama administration to allow gay men to donate blood. The lawmakers say the administration should change what they say is an "outdated" policy. Eighty-two lawmakers in the House and Senate signed on to the letter, including Sens. Tammy Baldwin (D-Wis.), Mike Enzi (R-Wyo.) and Elizabeth Warren (D-Mass.). Enzi was the only Republican to sign the letter. They said Department of Health and Human Services (HHS) Secretary Kathleen Sebelius should re-evaluate blood donation criteria that ban gay men from donating blood for life.
