Republican presidential candidate Rick Santorum has suspended his campaign. In addition, he has decided to endorse his fellow Republican Marco Rubio in the Presidential Campaign 2016.

The announcement came on Wednesday when the former Pennsylvania senator made it official on Fox News. Santorum said he made the decision after having discussed it with his wife, Karen. The decision was made after the Iowa caucuses, he said.

“We decided that we could be better advocates in supporting someone who shared those values and will do better in this race,” Santorum said as he talked about endorsing the Florida senator. According to him, Rubio can “bring the country together.”

“We wanted to find a candidate that really espoused the values we believed in,” Santorum said.

The Republican candidate had a dismal run at the Iowa caucuses. He managed only one percent of the vote and finished at the 11th position. When he ran for the Republican nomination in 2012, he won the Iowa caucuses.

Santorum, however, is not the first candidate to suspend the presidential campaign. Former Arkansas Gov. Mike Huckabee and Kentucky Sen. Rand Paul dropped out of the race earlier this week.

A number of things, which helped Santorum in 2012, did not work for him this time. He lost a few key consultants to his fellow Republicans. His former Iowa consultant, Chuck Laudner, works for Donald Trump this time. His former campaign manager, Michael Biundo, joined Paul. A couple of former spokesmen signed with Huckabee.

For the Democrats, it is now a one-on-one race between Hillary Clinton and Bernie Sanders as former Maryland Gov. Martin O’Malley suspended his campaign on Monday.

When CNN earlier asked Rubio about the possible endorsement from Santorum, he said he had not spoken to his fellow Republican that day.

“I think he’s fantastic,” Rubio said about Santorum.

According to The Washington Post, Santorum’s disabled daughter Bella is at the heart of his political career. He has seven children with his wife Karen.
