Rick Santorum confirms end of 2016 presidential campaign and endorses Marco Rubio

Rick Santorum suspended his campaign for the U.S. Republican presidential nomination on Wednesday and said he would endorse Senator Marco Rubio in the race for the White House.

Santorum, a 57-year-old former U.S. senator from Pennsylvania, won the Iowa caucuses four years ago, but managed only 1 percent of the vote in the Iowa contest on Monday.
