Gov. Rick Perry issued this statement on Cain’s decision to suspend his presidential campaign:

"I know this was a difficult decision for Herman Cain, his family and his supporters. He helped invigorate conservative voters and our nation with a discussion of major tax reform. Anita and I wish him and his entire family all the best."

Here is Rep. Ron Paul’s statement:

“Herman Cain brought energy and enthusiasm to the Republican nominating process, as well as a unique perspective on many domestic issues important to voters such as tax code reform and a pro-growth agenda favorable to the private sector.

“In light of his suspension of campaign activities, I want to wish Herman success in his future endeavors.”
