Santorum ends presidential bid, backs Rubio

WASHINGTON — Rick Santorum, the former Pennsylvania senator, ended his bid for the White House Wednesday and threw his support to Republican rival Marco Rubio.
"When it comes to the issues that we care about the most – restoring the American dream for hardworking families, standing up for the rights of the unborn, protecting our nation's security, and fighting for international religious freedom – we believe Marco Rubio's position are right on, and he has earned our endorsement," Santorum said in a message sent to supporters Wednesday night.
