(FOX 11 / FOX News) - Former Pennsylvania Sen. Rick Santorum plans to announce he is suspending his 2016 presidential campaign Wednesday night, sources tell FOX News.
The decision comes after a poor showing in Monday's Iowa caucuses.
Santorum came in 11th place and picked up just 1 percent of the Iowa vote, despite winning the caucuses when he ran for the Republican nomination four years ago.
Santorum would be the fourth White House hopeful to drop out of the race this week.
Earlier Wednesday, Kentucky Sen. Rand Paul announced he would suspend his bid, following former Arkansas Gov. Mike Huckabee in leaving the race. On the Democratic side, former Maryland Gov. Martin O’Malley, who placed a distant third in caucuses, also announced Monday he would drop out.
Santorum is scheduled to be a guest on FOX News' "On the Record with Greta Van Susteren" Wednesday night at 7 p.m. ET.
