SANAA, Yemen (AP) - A senior White House envoy has asked Yemen's president to sign a deal that would have him transfer power to his vice president and step down in exchange for immunity from prosecution.
 
President Ali Abdullah Saleh has promised in the past to sign the deal, brokered by Gulf countries, then balked at the last minute.
 
White House counterterrorism chief John Brennan met Saleh on Sunday, in the strongest sign yet of U.S. pressure. The two met at a hospital in Saudi Arabia where Saleh is recovering from wounds sustained in an attack on his presidential compound last month.
 
The White House says Brennan urged Saleh to sign the pledge "expeditiously." Brennan says "assistance will flow to Yemen" when the deal is implemented.
