Organ banks around the country have noted an increasing number of organs from donors who have died of overdoses.
Three Republican senators who met Tuesday with U.N. Ambassador Susan Rice say they are more troubled now over her initial explanations about the deadly Sept. 11 raid in Libya.
Rice met behind closed doors Tuesday with Sens. John McCain, Lindsey Graham and Kelly Ayotte – three of her harshest critics.
Ayotte said Rice told them that her national television description that a spontaneous demonstration triggered the attack on the U.S. consulate was wrong. She had made the comments five days after the raid based on intelligence information.
The lawmakers said the Obama administration still must answer questions about the attack.
Obama is considering Rice as a successor to Secretary of State Hillary Rodham Clinton.
